deliver continuous power in excess of 1 kW or up to 4 kW

for a short period to a three−phase motor. The foremost

circuitries conforming the system are, the auxiliary power

supplies, the current and voltage sensing, the overcurrent

protection, and of course the three−phase inverter, build with

the NFAM5065L4B IPM. Figure 4 illustrates the overall

view of the above circuitries.

new solutions.

Protection function in the system include under−voltage

lockout, and external hardware shutdown for over−current

protection via a comparator−based trigger event, which is

currently configured at +21 A via the current sense and

voltage−divider selection. By changing the voltage divider

resistors, the designer can change the over−current

protection threshold. Finally, external shutdown via

software is also possible (via CIN pin), allowing the user to

define a multilayer current protection function.

Inverter Stage with Intelligent Power Module (IPM)

Technology

The inverter power stage is the backbone of this

development board and it performs the DC/AC conversion.

It utilizes the NFAM5065L4B IPM module, a fully integrated

power stage for three−phase motor drives consisting of six

IGBTs with reverse diodes, an independent high side gate

driver, LVIC, and a temperature sensor (VTS). The IGBT’s

are configured in a three−phase bridge with separate emitter

connections for the lower legs to allow the designer

flexibility in choosing the current feedback topology and

resolution. This module leverages the Insulated Metal

Substrate (IMS) technology from ON Semiconductor.

Packaged in the DIP39 format, the NFAM5065L4B (from

here on IPM) not only provides a highly integrated, compact

and rugged solution, but also best−in−class thermal

management capabilities. In short, the module enables lower

component count designs for industrial motor drives and

In this development board the DC−Link, which is

provided by an external power supply, serves as the power

input to the inverter module. The module needs to be

supplied as well with 15 Vdc, necessary for the IGBT gate

drivers, 5 Vdc necessary for the MDK_SPM31, as well as

with 3.3 Vdc voltage necessary for the current measurement

Op−Amps and over−current protection comparators. The

auxiliary power supplies that have been referred earlier

(NCP1063, FAN8303, and NCP718) in the document

provide these voltage rails.

IPM_FAULT and T_MODULE (temperature) are the

output signals from the IPM module, which are routed to the

UCB controller and can be used by the end−user for control

and protection purposes. All operational input and output

signals and the corresponding voltage references are

32−Bit−wide 256 MByte DDR3 SDRAM, on−board

Ethernet phy, 10 ADC channel – using ON Semiconductor

UCB is an industrial−grade System on Module (SoM) that

can be used for advanced networked motor and motion

control systems, capable of delivering advanced control

strategies for different types of motors (AC induction motor,

PMSM, BLDC).

The UCB controller interacts with the power board via

specific pins, which are routed to two − 120 pins each –

connectors. More details around the connectors can be found

in Board Connectors. Auxiliary 5 Vdc and 3.3 Vdc power

supplies can be used for powering−up the UCB board. They

are located at the main power board. Alternatively, the UCB

can be powered−up from the 5 Vdc USB cable, which is

connected to the controller. Then, the UCB generates all the

voltage rails (3.3 Vdc included) that are required for its

proper operation. In addition, it also delivers (independently

of the main auxiliary supplies) the necessary 5 Vdc and

3.3 Vdc reference voltages for the Op−Amps and

comparators on the power board. Therefore, functionality of

the controller, as well as the functionality of the Op−Amps

and comparators can be evaluated even when the main

power board auxiliary supplies are off.

in Low−power Connectors, High−power Connectors, and in

Appendix. The applied design has been influenced by the

AND9390/D [10] and the NFAM5065L4B [2] data sheet.

Current Measurement

The development system is round out by the NCS2250

High Speed Comparator, the NCS20166 precision

low−offset Op−Amp, and the NCD98011 UCB integrated

ADC module. Currently, ADC resolution is 11−bit resulting

in an overall resolution of 0.016 A/bit, while the range of

phase−current measurement is set to 16.5 A. The

NCS20166 gain selection, the current sense resistor

selection, and the NCD98011 ADC module that is integrated

in UCB define the overall current resolution. The overall

resolution and maximum current range can be found in

Table 1. More details around the SAR concept and

NCD98011 can be found in [9].

DC−Link and Inverter Phase−voltages Measurement

The DC−Link and inverter phase−voltage are both sensed

via resistive voltage divider circuits, where the scaled−down

voltage signals are used as inputs for the integrated UCB

ADC −NCD98011 − modules. As mentioned above, overall

resolution and maximum voltage range can be found in

Table 1.

Finally, the UCB provides the control capabilities of the

system, and supports the user interface communication. End

user can develop its own applications to exploit the UCB

features and capabilities. As mentioned earlier the

MDK_SPM31 power board provides all the required

feedback to the UCB for the generation of PWM driving

signals to control the IGBT module gate drivers as well as

to enable/disable the module in the event of faults arising.

This allows end−user to develop many different control

strategies from simple V/F and Field Oriented Control

(FOC) up to predictive control algorithms. Moreover, the

UCB enables bidirectional serial communication to transfer

measurements data for visualization purposes. A Graphical

User Interface is provided, along with an appropriate code

in flash that can run a simple V/F control or an FOC and

allow visualization of key electrical quantities. More details

around the software can be found in Software section. The

interface header pinout of MDK_SPM31 is described in

detail in Board Connectors. A detailed description of the

UCB connector can be found in Appendix. Finally, the

documentation around UCB can be found in [1].

Over−current Protection and Under Voltage Protection

Fault

The hardware over−current protection leverages the

disable−option on the IPM. This function exploits the

disable pin (CIN pin) of IPM, via the ITRIP signal that is

provided to the power module by the NCS2250 comparator.

The disable−pin (CIN pin) is also controlled by UCB

controller, allowing the end−user to configure a multilayer

overcurrent protection. Finally, the end−user may also

leverage the output fault signal of IPM (VFO), using the

UCB controller. Note that VFO output is routed to UCB. As

such, when a fault arises the software can use VFO output

accordingly to shut down system operation or take other

actions. Note that the above protection mechanism is

implemented in software level, and as such it might be

subjected to delays or spurious tripping if not properly

handled.

UCB Controller

The UCB is a powerful universal motor controller that is

based on SOC Zynq 7000 series [11]. It includes a dual

667 MHz CPU Cortex A9 core, with freely configurable

Auxiliary Power Supplies

supplies can be found in the corresponding ICs data sheets,

[3], [4], and [5], respectively. Last but not least, the power

rating of the auxiliary power supplies can be found in

Table 1.

There are three auxiliary supplies on the power board to

provide the necessary 15 Vdc, 5 Vdc, and 3.3 Vdc rails. The

first one is a non−isolated buck converter using NCP1063.

This auxiliary supply provides the 15 Vdc, which are

necessary for the IPM drivers. The NCP1063 high−voltage

switcher serves well this purpose, featuring a built−in 700 V

EEPROM

The main power board is equipped with the CAT24C512

EEPROM unit. The CAT24C512 is an EERPOM Serial

MOSFET with R

of 11.4 ꢀ and 100 kHz switching

512−Kb I C, which is internally organized as 65,536 words

frequency. NCP1063 is fed directly from the high−voltage

DC−Link. A minimum 90 V DC−Link voltage is required

for operation. Next, the FAN8303 non−isolated buck is used

to convert the 15 Vdc to the 5 Vdc that is necessary for the

UCB controller circuitry. Last but not least, the LDO

NCP718 converts the 5 Vdc to 3.3 Vdc, necessary for the

current measuring and protection circuitry, and for the

integrated UCB NCD98011 ADC modules. The

non−isolated power supplies provides a simple and effective

solution for industrial and commercial motor control

applications. More details about the auxiliary power

of 8−bits each. It features a 128−byte page write buffer and

supports the Standard (100 kHz), Fast (400 kHz) and

2

Fast−Plus (1 MHz) I C protocol. External address pins

make it possible to address up to eight CAT24C512 devices

on the same bus. The device Serial Click and Serial Data pins

of the CAT24C512 (pins DIO_1_1, DIO_1_2) are routed to

the UCB controller B35 buss (B35_L16_N and B35_L16_P,

respectively), via CON4 (pin 13 and pin 14). The data sheet

of CAT24C512 EEPROM device can be found in [8].

SCHEMATIC AND DESIGN

To meet customer requirements and make the evaluation

board a basis for development, all necessary technical data

like schematics, layout and components are included in this

chapter. This section will also discuss the design remarks,

trade−offs and recommendations for the design.

15 Vdc auxiliary power supply. The design and sizing of the

passive components has been inspired by the applications

notes in [3]. The desired output voltage value can be set by

tuning the values of the voltage divider (R1 and R3)

connected to the FB pin. Additionally, the value of C6 on the

COMP pin is tuned empirically to reflect the desired voltage

at the converter output. It is noted that the frequency Jittering

function helps spreading out energy in conducted noise

analysis. To improve the EMI signature at low power levels,

the jittering remains active in frequency foldback mode.

Finally, the switching frequency is 100 kHz, which allows

designs with small inductor (for this design we used 560 ꢁ H,

see L2) and output capacitance requirements (for this design

we used two 220 ꢁ F, see C8 and C9) and low current ripple

output.

NCP1063 15 V Auxiliary Power Supply

As mentioned earlier, there are three Auxiliary power

supplies that generate the necessary voltage rails for the

proper function of the MDK_SPM31 and UCB controller

boards. The NCP1063 is a non−isolated buck that is used as

converter from DC−Link to 15 Vdc output, to supply the

IPM board, as well as the UCB board and Op−Amp circuitry

through the FAN8303 and NCP718. The maximum power

demand is up to 4.6 W. Figure 5 depicts the schematic of the

Figure 5. Schematic of Auxiliary 15 Vdc Power Supply

SECO−MDK−4KW−65SPM31−GEVB

FAN8303 and NCP718 Auxiliary Power Supplies

The FAN8303 is a non−isolated buck that is used as

converter from 15 Vdc to 5 Vdc output. The maximum

power demand is 2.9 W. Figure 6 depicts the schematic of

the 5 Vdc auxiliary power supply. Similarly to the

NCP1063, the design and sizing of the passive components

has been inspired by the applications notes in [4]. The

desired output voltage value can be set by tuning the values

of the voltage divider (R5 and R6) connected to the FB pin.

Additionally, the value of C17 on the COMP pin is tuned

empirically to reflect the desired voltage at the converter

output. The controller operates at fixed 370 kHz with an

efficiency up to 90%. This allows a design with only 22 ꢁ H

magnetizing inductance (see L3) and two 22 ꢁ F capacitors

(see C13 and C14). Finally, Figure 6 depicts the NCP718

LDO, which is responsible for the 3.3 Vdc rail generation.

circuitry around it. Finally, Figure 8 depicts the DC−Link

voltage (voltage divider containing R46, R52, R53 and R55)

and the inverter output phase−voltage measurement

circuitry (voltage divider for phase−U containing R31, R34,

R40 and R42; voltage divider for phase−V containing R32,

R35, R41 and R43; and voltage divider for phase−W

containing R29, R33, R39 and R44). The inverter output

voltage phases can be used by the software for zero crossing

detection or other control purposes. The signals from the

10 mꢀ shunt resistors are going to current measurement and

over−current protection circuits. Details regarding the ADC

resolution of the above sensed electrical quantities can be

found in Table 1. Next paragraphs are dedicated to the

elaboration of the above mentioned circuitries.

This subsection shows how the necessary circuitry for

operation, measurement and protection is setup around the

NFAM5065L4B IPM. In addition, it illustrates the necessary

circuitry to provide and capture the signals around the

module (i.e. the output signals: T_MODULE, IPM_FAULT;

and the input signals: ITRIP, IPM_DIS, and gate driver

signals INH_U, INH_V, INH_W, INL_U, INL_V, INL_W).

Finally, it illustrates the provision of the voltage rails for the

IPM (15 Vdc rail reference), as well as the measurement of

the DC−Link and inverter−phase voltages. Activation of

IPM stage (connection to 15 Vdc power supply) is via J1

(soldered pads). Figure 7 shows the J1 pads at the bottom

side of the board; mind that pads should be soldered together

to enable the 15 Vdc to the IPM. Following, Figure 8 shows

Please note that the inverter phase voltage measurement

with the currently used resistors will be saturated for

DC−Links higher than 241.7 V, as demonstrated in the

figures below. However, this configuration allows detection

of the zero crossing BEMF with increased accuracy, as you

can compare the inverter output phase with the half of the

DC−Link voltage. It should be noted that with the currently

used resistor network, the inverter output phase−voltage

could be used only to detect the BEMF zero crossing for

trapezoidal−type controls with respect to the half of the

DC−Link voltage. For different zero−crossing detection

methods, such as the reconstruction of inverter neutral

voltage in software, or for different control algorithms

where the full range of inverter phase voltages is required,

you should replace the three bottom 13.7 kꢀ resistors R42,

R43, R44 with 6.8 kꢀ ones. The main reason of using this

limited voltage range for the inverter output phase is to

increase the voltage resolution around the BEMF zero

crossing, where only two out of three inverter phases are

energized.

to CIN, Figure 8). CIN pin is also controlled by the UCB

controller, which allows the end−user to design multilayer

protection. Comparator threshold is set by a voltage divider,

which consists of the R65 and R69 resistors. That threshold

is compared against the non−inverting pin voltage, which

comes from the voltage across the shunt resistors R60, R64

and R66. The comparator also incorporates a hysteresis loop

by providing a feedback to the non−inverting pin via the R63

resistor. Based on the above selected resistors the tripping

threshold corresponds to +21 A. To prevent spurious

operation of comparator, a low pass filter is implemented,

formed by the capacitor C68 along with resistors R60, R64,

and R65. The cut−off frequency of the formed low−pass

filter results in a delay of around 500 ns, which is sufficient

for the fast reaction of the current protection.

On top of that, IPM asserts fault pin (VFO), which can be

used by the UCB to shut down the inverter. The voltage level

of that pin is low during normal state. After a fault

occurrence at the driver, the output of fault pin is switched

high. The output of fault pin is held on for a time determined

by the C44 capacitor (15 nF) that is connected to the CFOD

pin (IPM pin 25), which can be used by the software for

further actions. The equation that gives the on time of the

Low−power Connectors

The MDK_SPM31 board has seven connectors in total.

Five of those connectors (CON7, CON6, J4, and CON4 and

CON5,) interfere with the various low−power signal and

voltage rails, while the rest two connectors handle the high

dc−input and the three−phase ac−output high power

voltages.

Figures 13−15 depict the low power connectors

schematics of the board along with their physical

visualization.

CON7 (Figure 13) can be used as an interface between the

encoder and the UCB controller, enabling sensored−FOC

control algorithms.

The connector CON6 gives access to additional digital

I/O, PWM, and ADC pins of the UCB controller. Low pass

filters for current and/or voltage measurement signals are

placed closed to the headers (see Figure 14).

Board Connectors

MDK_SPM31 comes with several connectors that allow

the board to interact with external systems, such as encoders

and different control platforms (i.e. UCB). MDK_SPM31

also carries the appropriate connectors to host the UCB

low−power connectors are routed to the UCB controller via

CON4 and CON5. On the contrary, signals like the

SOFTWARE

FOC has been widely used during the last decade as an

executable Serial_Gui file. With the GUI, the user can select

between the V/F and FOC strategy. The GUI also assists the

end−user to configure and tune the foremost V/F and FOC

parameters, while it also provides visual representation of

key electrical variables, such as the DC−Link voltage and

temperature of IPM, the RMS value of the inverter output

current and voltage, and the motor speed.

efficient way to control various types of motors over wide

speed ranges. The controller optimizes the efficiency of the

system as it produces the required motor torque with the

lowest possible phase−currents, by maintaining a 90o angle

between the rotor flux and current. Moreover, it provides

fast dynamic response and a low current harmonic content.

Numerous scientific and technical papers in literature

describe thoroughly the FOC operation. We would like to

note that the analysis of FOC falls beyond the scope of this

document. For a more comprehensive description of FOC

operation, the reader may refer to the corresponding

references. [13−15].

Rewriting Flash Memory or SD−card Image

(Important when UCB not acquired as part of the

SECO−MDK−4KW−65SPM31−GEVK)

In case the user wants to rewrite the flash memory with the

default V/F−FOC control, he can use the boot−image and

fsbl.elf files that are accessible via the link in [12]. To

download the boot−image and fsbl.elf, click the link in [12]

and download the latest version of software; boot−image

and fsbl.elf files are included in the UCB_firmware of the

downloaded software file.

UCB with Pre−flashed Firmware

(UCB acquired as part of SECO−MDK−4KW−65SPM31−

GEVK)

If you acquired the UCB as part of the ON Semiconductor

kit, the controller is already flashed with V/F control and

FOC control. The user does not have to perform any further

actions for booting. It is noted however, that booting from

the flash, the SD−socket at UCB should be empty. With the

flashed controller, the user can control the motor via the

graphical user interface (GUI) of Figure 19; to download the

GUI, click the link in [12], download the latest version of

software, open the MDK_GUI zip file, and run the

Ground Potential

The ground potential of the system is biased to a negative DC bus voltage potential. When

measuring voltage waveform by oscilloscope, the scope’s ground needs to be isolated.

Failure to do so may result in personal injury or death.

USB Isolation

The ground potential of the system is NOT biased to an earth (PE) potential. When

connecting the MCU board via USB to the computer, the appropriate galvanic isolated USB

isolator have to be used. The recommended isolation voltage of USB isolator is 5 kV.

DC BUS Capacitors

SECO−MDK−4KW−65SPM31−GEVB system contains DC bus capacitors which take time

to discharge after removal of the main supply. Before working on the drive system, wait ten

minutes for DC BUS capacitors to discharge to safe voltage levels. Failure to do so may

result in personal injury or death.

4

Trained Personnel

Only personnel familiar with the drive and associated machinery should plan or implement

the installation, start−up and subsequent maintenance of the system. Failure to comply may

result in personal injury and/or equipment damage.

Hot Temperature

ESD

The surfaces of the NFAM5065L4B and development board drive may become hot, which

may cause injury.

SECO−MDK−4KW−65SPM31−GEVB system contains parts and assemblies sensitive to

Electrostatic Discharge (ESD). Electrostatic control precautions are required when

installing, testing, servicing or repairing this assembly. Component damage may result if

ESD control procedures are not followed. If you are not familiar with electrostatic control

procedures, refer to applicable ESD protection handbooks and guidelines.

Installation and Use

A drive, incorrectly applied or installed, can result in component damage or reduction in

product lifetime. Wiring or application errors such as under sizing the motor, supplying an

incorrect or inadequate AC supply or excessive ambient temperatures may result in system

malfunction.

Powering Down the System

Remove and lock out power from the drive before you disconnect or reconnect wires or

perform service. Wait ten minutes after removing power to discharge the DC bus

capacitors. Do not attempt to service the drive until the bus capacitors have discharged to

zero. Failure to do so may result in personal injury or death.

electrical equivalent of the R−L load along with the

electrical quantities under measured. The experimental

results and captured waveform are depicted in Figures

22−27, showing the captured current and voltage

waveforms, along with the reading from the DC−power

supply. Thermal analysis results from FLIR A645SC

camera conclude the section.

Table 3 summarizes the electrical parameters that have

been used for the test, as well as the values of the electrical

quantities that we have measured. The recorded efficiency

was 95% and 96% respectively.

This section presents the results of the experimental test

performed on the board. For the experimental test we have

used an R−L load which is rated up to 4 kW, instead of

a motor. The IPM switching frequency is set to 16 kHz,

while the dead−time of the IPM is set 1500 ns. Finally, the

DC−Link is set to 400 V, via a DC−power supply. The

equivalent R−L emulates the motor and consists of three

inductors (5 mH per phase) connected in series with

a resistive bank that comprises variable resistors from

7.55 ꢀ up to 30 ꢀ per each phase. The above configuration

forms an equivalent three−phase R−L load in Y connection,
