The ARM (Autoranging Rectifier Module) is an
AC front end module which provides autoranging
line rectification and inrush current limiting. The
ARM is available in either 500/750 W or
750/1500 W models in a quarter brick package
measuring only 2.28" x 1.45" x 0.5".
The ARM interfaces directly with worldwide AC
mains and may be used with Vicor
300 V input DC-DC converters to realize an
autoranging, high density, low profile switching
power supply. The ARM includes a
microcontroller that continuously monitors the
AC line to control bridge/doubler operation. The
user need only provide external capacitance to
satisfy system hold-up requirements.
Vicor Micro series packaging technology offers
flexible mounting options for various
manufacturing processes. The ARM may be
installed as a conventional leaded device for onboard applications, in-board for low profile,
height restricted applications, socketed or surface
mounted with optional ModuMate interconnect
products.

APPLICATION NOTE
The VI-ARM Autoranging Rectifier Module (ARM) provides
an effective solution for the AC front end of a power supply
designed with Vicor DC-DC converters. This high performance
power system building block satisfies a broad spectrum of
requirements and agency standards.
2.1
If the bus voltage is less than 200 V 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 200 V, the doubler is
not activated.
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
configuration, the user needs only to add holdup capacitors and
a suitable input filter with transient protection.
3.1
If the bus voltage is greater than 235 V as the slope
approaches zero, the inrush limiting thermistor is
bypassed. Below 235 V, 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
delay to allow the converter outputs to settle within
specification.
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 Fig. 8). In addition, the
downstream DC-DC modules are disabled via the Enable (EN)
line, and Bus-OK (B OK) is high.
1.2
Bus-OK is deasserted when the bus voltage falls below
205 Vdc (Typ.).
Power-Up Sequence. (See Fig. 9).:
2.2
The converters are disabled when the bus voltage falls
below 200 Vdc. 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.
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.
Power-Down Sequence. (See Fig. 9). When input power is
turned off or fails, the following sequence occurs as the bus
voltage decays:

APPLICATION NOTE (CONT.)
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
15 V through a 150 kΩ resistor.
Off-Line Power Supply Configuration
The ARM maintains the DC output bus voltage between 200
and 375 Vdc over 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 300 V 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 500 W
in the low range (90-132 Vac input), and 750 W in the high
range (180 – 264 Vac input). The VI-ARMB-x2 is rated for 750
W and 1500 W 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 (15 V) 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 400 Vdc. 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 less than 180 Vdc.
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.
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, Fig. 10)
for proper (autoranging) operation. Varistors across the
capacitors provide input transient protection. The bleeder
resistors (R1, R2, Fig. 10) discharge the holdup capacitors
when power is switched off.
Enable (EN) Pin. (See Fig. 11). The Enable pin must be
connected to the Gate-In or PC pin of all converter modules to
disable the converters during power-up. Otherwise, the

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.
Filter. Two input filter recommendations are shown for low
power VI-ARM-x1 and high power VI-ARMB-x2 (See Fig. 13).
Both filter configurations provide sufficient common mode and
differential mode insertion loss in the frequency range between
100 kHz and 30 MHz to comply with the Level B conducted
emissions limit.

Hold-up Capacitors. Hold-up capacitor values should be
determined according to output bus voltage ripple, power fail

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.

It should be noted that the series combination (C1, C2, Fig. 10)
requires each capacitor to be twice the calculated value,
but the required voltage rating is reduced to 200 V.
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.
For example, a converter whose output is 15 V and nominal
input is 300 V will provide 56 dB ripple rejection, i.e., 10 V p-p
of input ripple will produce 15 mV p-p of output ripple. (See
Fig. 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 Fig. 14) of
the ripple, respectively. The capacitors must hold up the bus
voltage for the time interval (Δt) between peaks of the rectified
line as given by:

The power fail warning time (Δt) is defined as the interval
between (B OK) and converter shutdown (EN) as illustrated in
Fig. 12. The Bus-OK and Enable thresholds are 205 V and
190 V, respectively. A simplified relationship between power
fail warning time, operating power, and bus capacitance is
obtained by inserting these constants:

In this example, the output required at the point of load is 12
Vdc at 320 W. Therefore, the output power from the ARM
would be 375 W (assuming a converter efficiency of 85%). The
desired hold-up time is 9 ms over an input range of 90 to 264 Vac.

Determining Required Capacitance for Power Fail
Warning. Fig. 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 820 μF.
Since two capacitors are used in series, each capacitor must
be at least 1,640 μF.

Determining Ride-through Time. Figure 16 illustrates ridethrough time as a function of line voltage and output power,
and shows that at a nominal line of 115 Vac, ride-through
would be 68 ms. Ride-through time is a function of line
voltage.

Determining Ripple Voltage on the Hold-up Capacitors.
Fig. 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 12 Vac.

Figure 18 — Converter ripple rejection vs. output voltage (typical)
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:
I rms = 2P/Vac

Determining the Ripple on the Output of the
DC-DC Converter. Fig. 18 is used to determine the ripple
rejection of the DC-DC converter and indicates a ripple
rejection of approximately 60 dB for a 12 Volt output. If the
ripple on the bus voltage is 12 Vac and the ripple rejection of
the converter is 60 dB, the output ripple of the converter due
to ripple on its input (primarily 120 Hz) will be 12 mV p-p.
Note that Maxi, Mini, Micro converters have greater ripple
rejection then either VI-200s or VI-J00s.

Vac = 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.
