The SPAFCBK-11G AC/DC power module is a MCU/DSP controlled, highly efficient front-end power supply. It incorporates
resonant-soft-switching technology to reduce component stresses, providing increased system reliability and very high power
conversion efficiency.
The PFC stage is digitally controlled using a state-of-the-art digital signal processing algorithm to guarantee best efficiency and
unity power factor over a wide operating range.
The main DC/DC stage (12.6 V / 3300 W) uses soft switching resonant techniques in conjunction with synchronous rectification. An
active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant
power systems.
The auxiliary DC/DC stage (54 VDC / 300 W) uses a soft switching resonant topology and is also protected with an active OR-ing
device for maximum reliability.
The DC/DC converter from the battery input (3600 W) provides power to the internal high voltage bus and allows the outputs to
continue up to 90 s during AC outage. The battery charger stage (52.5 V / 270 W) re-charges the battery backup unit (BBU).
Status information is provided with a front-panel LED. The RS485 bus allows full monitoring of the supply, including input and output
voltage, current, power, and internal temperatures. The same RS485 bus supports the bootloader to allow field update of the
firmware in the MCU and the DSPs.
The supply is cooled by a regulated fan and the air direction matches regular data center rack configurations. The fan speed is
adjusted automatically depending on the supply temperature.

Figure 1. SPAFCBK-11G Block Diagram
The SPSFCBK-18 power shelf houses 3 power supply units (PSU) and 3 battery back-up units (BBUs) and maximizes power
availability in demanding server, network, and other high availability applications.
The main 12.6 VDC output offers 6600 W power in 2+1 redundant operation on a single output busbar on the back side of the shelf,
which is directly connected to the output busbar of all PSUs. Power balancing between the units is ensured by an active current
share scheme.
The auxiliary 54 VDC output offer 600 W power in 2+1 redundant operation on a single output connector on the rear side of the shelf.
A wiring harness connects the PSU to the BBU and the power shelf. Each PSU has its own BBU and there is no direct interconnection
between the BBUs.

The Front-End is provided with a minimum hysteresis of 8 V during turn-on and turn-off within the ranges
Efficiency measured with Fan supplied externally and only main output loaded.
The AC-DC power supply exhibits an X-capacitance of only 5.2 µF resulting in only a low and short peak current
when the supply is connected to the mains. The internal bulk capacitor will be charged through an NTC which will
limit the inrush current.

CH1: Vin (500 V/div), CH2: Iin (10 A/div)
Power factor correction (PFC) is achieved by controlling the input current waveform synchronously with the input
voltage. A fully digital controller is implemented giving outstanding power factor results over a wide input voltage
and load ranges. The input current will follow the shape of the input voltage. If for instance the input voltage has a
trapezoidal waveform, then the current will also show a trapezoidal waveform.

High efficiency (see Figure 7) is achieved by using state-of-the-art silicon power devices in conjunction with soft-
transition topologies minimizing switching losses and a full digital control scheme. Synchronous rectifiers on the
output reduce the losses in the high current output path. The speed of the fan is digitally controlled to keep all
components at an optimal operating temperature regardless of the ambient temperature and load conditions.
Setup: Single unit in Shelf Slot1, VAC and V1 measurement at PCB level at the connector. Fan externally supplied.
Only main output loaded.

OUTPUT ISOLATION
Main, auxiliary and battery charger output and all signals are isolated from the chassis and protective earth
connection. However, the applied voltage between any of these voltages and chassis must not exceed 100 Vpeak
to prevent any damage to the supply.
The RS485 communication lines and shelf/rack addresses (RS485_D / RS485_DN / ADD3…5) are additionally
isolated from all others.
Internal to the module the main output ground (GR1, also connected directly to FAN_SUPPLY_R in the module), the
auxiliary ground (AUX_54V_R) and the battery charger ground (BAT_R) are interconnected through 10 Ω resistors to
prevent any circulating current within the supply. The signal ground (GR5) is connected with 0.33 Ω to the main
output ground.
Each of the power modules is separately connected to its Battery Backup unit (BBU). The BBU and PSU are designed to
support maximum 90 s of full load back-up time in case of an outage.
The battery is being re-charged by the 270 W (5 A /52.5 V) battery charger circuit in the PSU.
The BBU has 8 digital lines to the PSU with which it flags errors and requests operations (see also section 3.7).
Additionally, there is also an I2C communication between the PSU and the BBU which is implemented to allow the user to
access some of the battery registers via the RS485 interface.
BACKUP BEHAVIOR
If the AC input voltage is falling below Viac off or if the frequency is outside the valid operating range fi, the PSU is
changing to DC operation and taking the power from the BBU.
The power module implements a soft startup when transitioning to battery backup mode, limiting the current
overshoot as the bulk voltage is ramped back to a nominal level. No deviation occurs on the main output voltage.
Figure 14. Backup Transition CH1: V1 (2V/div) CH2: Ibatt (20A/div) Ch3: VBULK (20V/div) Ch4: VAC(200V/div)
After 45 s in DC operation the PWR_FAIL signal is set. After 90 s without AC return the PSU is shutting down and
only is restarting with a valid AC voltage restored.

V2 Power Module & V2 Power Shelf
If a valid AC voltage is re-applied after less than 90 s, the shelf is transitioning back to AC operation without any
deviation at the output. The time between AC voltage present and the transition from DC to AC operation is random
from one shelf to the other to reduce the stress on the AC supply.
BATTERY CHARGER BEHAVIOR
The BBU decides on its own if it needs to be re-charged. Charging is requested by setting the BAT_CRG_EN flag.
The PSU reacts on this flag by starting the 52.5 V battery charger with a controlled current ramp up.
If the battery charger is running for more than 5 consecutive hours it is shut down and a failure is flagged.
BBU STATE OF HEALTH CHECK
The BBU will determine internally with a random logic if it needs to be tested, and requests with the BAT_SOH_CHK
signal a test discharge.
The power modules in the shelf decide based on their own and the other modules state, if they can do such a
discharge. A state of health test discharge is only done if:
-
-
-
-
-
-
All 3 PSUs and BBUs are installed and communication is available
No other BBUs self-check is ongoing
No PSUs or BBUs failed
No BBU being charged at the moment
All PSUs in AC operation
PSU load is >500 W for at least 1 consecutive minute
The BBU will determine if the test was valid and decide if it has reached the end of life and set the BAT_EOL signal
if required.

LATCH-OFF AND CLEARING
If an error on the main 12.6 V output occurs which is latching off this converter, it will also shut down and latch the
auxiliary and battery charger converter.
If the auxiliary or the battery charger converter fail with a latching error, they will not shut down any of the other
converters.
The latching faults can be cleared/unlocked by disconnecting the supply from the AC mains for >2 s with a shutdown
of the main output (not going into backup mode), or by toggling the PS_KILL input.
INPUT FUSE
Fast-acting 25 A input fuse (6.3 x 32 mm) in series with the L-line inside the power supply protects against severe
defects. The fuse is not accessible from the outside and is therefore not a serviceable part.
AC INPUT UNDER-VOLTAGE
If the sinusoidal input voltage stays below the input undervoltage lockout threshold Vi on or falls below Vi off during
operation, the supply will be inhibited. Once the input voltage returns within the normal operating range, the supply
will return to normal operation again.
If a good battery back-up unit is present, the unit can keep on operating for up to 90 s in case of AC outage. More
details see in Section 3.4.
DC INPUT UNDER-VOLTAGE
There are several protection levels for the DC input under voltage. The BBU module will begin to protect itself at
33.8 V. Below this level, the PSU will protect at the Software under voltage threshold of 31.85 V, and this undervoltage
is ignored during the first 15 seconds of backup to account for temporary dips during current ramp up. Finally, below
this level is the hardware under voltage at 28 V.

OVERVOLTAGE PROTECTION
The SPAFCBK-11G front-end provides a fixed threshold overvoltage (OV) protection implemented with a HW
comparator for the main, the auxiliary and the battery charger output.
Once an OV condition has been triggered, the supply will shut down the converter.
The auxiliary and battery charger output have in addition to the HW overvoltage protection a software overvoltage
detection implemented.
UNDERVOLTAGE DETECTION
All three outputs have a software under voltage protection implemented.
If the main output voltage falls below the under voltage level V1 UV for a time > tV1 UV trip it will latch-off.
If the auxiliary output falls below the under voltage limit VAUX UV for a time > tVAUX UV trip the control circuit will attempt
to restart the converter, if voltage is not restored before tVAUX UV latch the output will latch-off.
If the battery charger falls below the under voltage limit VBC UV for a time > tVBC UV trip the control circuit will attempt to
restart the converter, and remain on indefinitely.
OUT OF REGULATION DETECTION BATTERY CHARGER
If the battery charger current is less than 300 mA (which indicates the battery is nearly charged), the voltage is
monitored to stay inside the regulation bandwidth. If the voltage is outside this band for more than tVBC out of reg the
control circuit will shut down the battery charger output and latch off.
CURRENT LIMITATION
The main output exhibits a substantially rectangular output characteristic controlled by a software feedback loop. If
the output current exceeds IV1 CL REG it will reduce the output voltage in order to keep the output current constant. If
the output current is higher than IV1 OC SW for more than tV1 OC SW latch the output will latch off.
A second current limitation implemented as a fast hardware detection circuit will immediately switch off the main
output if the output current increases beyond the peak current trip point, occurring mainly if a short circuit is applied
to the output voltage. The supply will re-start after tV1 OC HW restart with a soft start.

The auxiliary output exhibits a substantially rectangular output characteristic, controlled by a hardware feedback
loop. If the output current exceeds IVAUX CL REG it will reduce the output voltage in order to keep the output current
constant.
Running in current limitation causes the output voltage to fall, this will trigger the under voltage protection, see also
Undervoltage Detection.

V2 Power Module & V2 Power Shelf
The SPAFCBK-11G front-end has an active current share scheme implemented for V1. All the ISHARE current share
pins need to be interconnected in order to activate the sharing function. If a supply has an internal fault or is not
turned on, it will disconnect its ISHARE pin from the share bus. This will prevent dragging the output down (or up) in
such cases.
The current share function uses a digital bi-directional data exchange on a recessive bus configuration to transmit
and receive current share information. The controller implements a Master/Slave current share function. The power
supply providing the largest current among the group is automatically the Master. The other supplies will operate as
Slaves and increase their output current to a value close to the Master by slightly increasing their output voltage.
The voltage increase is limited to +250 mV.
The Auxiliary output uses a passive current share method (droop output voltage characteristic).
PSKILL input is an active-low recessed pin in the connector and is used to shut down the circuits as soon as the
power supply is being pulled out. This pin is connected to ground in the power shelf.

The PWR_FAIL signal indicates that the power supply is in risk of losing the output power in backup mode. It is
pulled low after 45s in backup operation if AC is not returned.
It is an open collector signal which needs to be pulled up to an external voltage. (See limits in Table 1.)
Figure 21. PWR_FAIL connection
The RED_LOST signal indicates that the shelf is not operating in redundancy anymore. It is pulled low if at least one
PSU or BBU in the shelf is failed, not operational or not present. The signal is not pulled low in case of a BAT_PROT
or BAT_STOP_DCRG event.
It is an open collector signal which needs to be pulled up to an external voltage. (See limits in Table 1.)

The SPAFCBK-11G front-end is a communication slave device only; it never initiates messages on the
RS485/MODBUS by itself. Communication to the MCU will be possible as long as the input AC voltage is provided
and above Von bias
.
For more information about the communication, see Communication Manual BCA.00072.
To achieve best cooling results sufficient airflow through the supply must be ensured. Do not block or obstruct the
airflow at the rear of the supply by placing large objects directly at the output connector. The SPAFCBK-11G is
provided with a front to rear airflow, which means the air enters through the front panel of the supply and leaves at
the connector side. The SPAFCBK-11G supply has been designed for horizontal operation.
The fan inside of the supply is controlled by a microprocessor. The RPM of the fan is adjusted to ensure optimal
supply cooling and is a function of the inlet, outlet and critical component temperatures. There is no direct
dependency on the delivered power.
The SPAFCBK-11G provides access via RS485 to the measured temperatures of in total 8 sensors within the
power supply, see Table 3. The microprocessor is monitoring these temperatures and increases the fan speed
based on those. If a critical level is reached, the temperature warning bit is set. If temperatures continue to rise
above the shut down threshold all outputs will be disabled. At the same time the warning or fault condition is
signaled accordingly by a LED (see LED signaling in Table 2).
