2.1. If the bus voltage is less than 200V as the slope nears zero,

the voltage doubler is activated, and the bus voltage climbs

exponentially to twice the peak line voltage.

If the bus voltage is greater than 200V, the doubler is

not activated.

Application Note

The VI-ARM Autoranging Rectiﬁer Module (ARM) provides an

effective solution for the AC front end of a power supply design

with Vicor DC-DC converters. This high performance power syst

building block satisﬁes a broad spectrum of requirements and

agency standards.

hes

3.1. If the bus voltage is greater than 235V as the slope approac

zero, the inrush limiting thermistor is bypassed. Below 235V,

The ARM contains all of the power switching and control

circuitry necessary for autoranging rectiﬁcation, inrush current

limiting, and overvoltage protection. This module also provides

converter enable and status functions for orderly power up/

down control or sequencing. To complete the AC front-end

the thermistor is not bypassed.

4.1. The converters are enabled ~150 milliseconds after the

thermistor bypass switch is closed.

5.1. Bus-OK is asserted after an additional ~150 millisecond dela

to allow the converter outputs to settle within

speciﬁcation.

conﬁguration, the user needs only to add holdup capacitors and a

suitable input ﬁlter with transient protection.

Power-Down Sequence: (See Figure 9). When input power

is turned off or fails, the following sequence occurs as the bus

voltage decays:

Functional Description

Initial Conditions: The switch that bypasses the inrush limiting

PTC (positive temperature coefﬁcient) thermistor is open when

power is applied, as is the switch that engages the strap for

voltage doubling. (See Figure 8). In addition, the downstream

DC-DC modules are disabled via the Enable (EN) line, and Bus-O

(B OK) is high.

1.2. Bus-OK is deasserted when the bus voltage falls below

205V_DC(Typ).

2.2. The converters are disabled when the bus voltage falls belo

200V_DC. If power is reapplied after the converters are disabled,

the entire power-up sequence is repeated. If a momentary

power interruption occurs and power is reestablished before

the bus reaches the disable threshold, the power-up sequence

is not repeated.

Power-Up Sequence (See Figure 9):

1.1. Upon application of input power, the output bus capacitors

begin to charge. The thermistor limits the charge current, and

the exponential time constant is determined by the holdup

capacitor value and the thermistor cold resistance. The slope

(dV/dt) of the capacitor voltage approaches zero as the

capacitors become charged to the peak of the

AC line voltage.

Enable (EN) Pin: (See Figure 11) The Enable pin must be

Application Notfe (Cont.)

connected to the Gate-In or PC pin of all converter modules to

disable the converters during power-up. Otherwise, the

converters would attempt to start while the holdup capacitors

were being charged through an un-bypassed thermistor,

preventing the bus voltage from reaching the thermistor bypass

threshold thus disabling the power supply. The Enable output

(the drain of an N channel MOSFET) is internally pulled up to 15V

through a 150kΩ resistor.

Off-Line Power Supply Conﬁguration

The ARM maintains the DC output bus voltage between 200 and

375V_DCover the entire universal input range, this being compatible

with Vicor VI-260 series and VI-J60 series DC-DC converters, as

well as Vicors Maxi, Mini, Micro 300V input Vicor converters.

The ARM automatically switches to the proper rectiﬁcation

mode (doubled or undoubled) depending on the input voltage,

eliminating the possibility of damage due to improper line

connection. The VI-ARM-x1 is rated at 500W in the low range

(90-132V_ACinput), and 750W in the high range (180 – 264V_AC

input). The VI-ARMB-x2 is rated for 750W and 1500W for the

low and high input ranges respectively. Either of these modules

can serve as the AC front end for any number and combination of

compatible converters as long as the maximum power rating is not

exceeded. See VI-ARMB derating curves. (Figures 1, and 2)

A signal diode should be placed close to and in series with the

PC/Gate-In pin of each converter to eliminate the possibility of

control interference between converters. The Enable pin switches

to the high state (15V) with respect to the negative output power

pin to turn on the converters after the power-up inrush is over.

The Enable function also provides input overvoltage protection

for the converters by turning off the converters if the DC bus

voltage exceeds 400V_DC. The thermistor bypass switch opens if this

condition occurs, placing the thermistor in series with the input

voltage, which reduces the bus voltage to a safe level while limiting

input current in case the varistors conduct. The thermistor bypass

switch also opens if a fault or overload reduces the bus voltage to

Strap (ST) Pin: In addition to input and output power pin

connections, it is necessary to connect the Strap pin to the junction

of the series holdup capacitors (C1, C2, Figure 10) for proper

(autoranging) operation. Varistors across the capacitors provide

input transient protection. The bleeder resistors (R1, R2, Figure 10)

discharge the holdup capacitors when power is switched off.

less than 180V_DC

CAUTION: There is no input to output isolation in the ARM, hence the

–OUT of the ARM and thus the –In of the downstream DC-DC converter(s)

are at a high potential. If it is necessary to provide an external enable/

disable function by controlling the DC-DC converter’s PC pin (referenced to

the –IN) of the converter an opto-isolator or isolated relay should

be employed.

Application Note (Cont.)

Caution: There is no input-to-output isolation in the ARM. It is necessary

to monitor Bus-OK via an optoisolator if it is to be used on the secondary

(output) side of the converters. A line isolation transformer should be used

when performing scope measurements. Scope probes should never be applied

simultaneously to the input and output as this will destroy the module.

Hold-up Capacitors: Hold-up capacitor values should be

determined according to output bus voltage ripple, power fail hold-

up time, and ride-through time. (See Figure 14). Many applications

require the power supply to maintain output regulation during a

momentary power failure of speciﬁed duration, i.e., the converters

must hold-up or ride-through such an event while maintaining

undisturbed output voltage regulation. Similarly, many of these same

systems require notiﬁcation of an impending power failure in order to

allow time to perform an orderly shutdown.

The power fail warning time (∆t) is deﬁned as the interval

between (B OK) and converter shutdown (EN) as illustrated in

Figure 12. The Bus-OK and Enable thresholds are 205V and

190V, respectively. A simpliﬁed relationship between power fail

by inserting these constants:

required voltage rating is reduced to 200V.

Operating Power (W)

Allowable ripple voltage on the bus (or ripple current in

the capacitors) may deﬁne the capacitance requirement.

Consideration should be given to converter ripple rejection and

resulting output ripple voltage.

Figure 15 — Power fail warning time vs. operating power and

total bus capacitance, series combination of C1, C2

(see Figure 10)

For example, a converter whose output is 15V and nominal input

is 300V will provide 56dB ripple rejection, i.e., 10Vp-p of input

ripple will produce 15mVp-p of output ripple. (See Figure 18)

Equation 3 is again used to determine the required

capacitance. In this case, V1 and V2 are the instantaneous

values of bus voltage at the peaks and valleys (see Figure 14)

of the ripple, respectively. The capacitors must hold up the bus

voltage for the time interval (∆t) between peaks of the rectiﬁed

line as given by:

Application Note (Cont.)

Example

In this example, the output required at the point of load is 12V_DC

at 320W. Therefore, the output power from the ARM would be

375W (assuming a converter efﬁciency of 85%). The desired hold-

up time is 9ms over an input range of 90 to 264V_AC

Determining Required Capacitance for Power Fail Warning:

Figure 15 is used to determine hold-up capacitance for a given

power fail warning time and power level, and shows that the total

bus capacitance must be at least 820µF. Since two capacitors are

used in series, each capacitor must be at least 1,640µF.

Note: The warning time is not dependent on line voltage. A hold-up

capacitor calculator is available on the Vicor website,

at vicorpower.com/hubcalc.

Figure 17 — Ripple voltage vs. operating power and bus

capacitance, series combination of C1, C2

(see Figure 10)

Determining Ripple Voltage on the Hold-up Capacitors:

Figure 17 is used to determine ripple voltage as a function of

operating power and bus capacitance, and shows that the ripple

voltage across the hold-up capacitors will be 12V_AC

Determining the Ripple on the Output of the

DC-DC Converter: Figure 18 is used to determine the ripple

rejection of the DC-DC converter and indicates a ripple rejection

of approximately 60dB for a 12 Volt output. If the ripple on the

bus voltage is 12V_ACand the ripple rejection of the converter is

60dB, the output ripple of the converter due to ripple on its input

(primarily 120Hz) will be 12mVp-p.

Note: Maxi, Mini, Micro converters have greater ripple rejection then either

VI-200s or VI-J00s.

power supply using the ARM and Vicor DC-DC converter modules,

Output Voltage

Storage

Another consideration in hold-up capacitor selection is their

ripple current rating. The capacitors’ rating must be higher than

the maximum operating ripple current. The approximate

operating ripple current (RMS) is given by:

Vicor products, when not installed in customer units, should be

stored in ESD safe packaging in accordance with ANSI/ESD S20.20,

“Protection of Electrical and Electronic Parts, Assemblies and

Equipment” and should be maintained in a temperature controlled

factory/ warehouse environment not exposed to outside elements

controlled between the temperature ranges of 15°C and 38°C.

Humidity shall not be condensing, no minimum humidity when

stored in an ESD compliant package.

I_RMS= 2P/V_AC

Where:

P = operating power level

_AC= operating line voltage

Calculated values of bus capacitance for various hold-up time,

ride-through time, and ripple voltage requirements are given

as a function of operating power level in Figures 15, 16, and

17, respectively.
