The FARM (Filter/Autoranging Rectifier
Module) is an AC front-end module which
provides EMI filtering, autoranging line
rectification and inrush current limiting. The
FARM is available in either 500/750W or
750/1000W models in a mini sized package
measuring only 2.28" x 2.2" x 0.5".
The FARM interfaces directly with
worldwide AC mains and may be used with
Vicor 1st or 2nd Generation 300V input
DC-DC converters to realize an autoranging,
high density, low profile switching power
supply. The FARM 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 2nd Generation packaging technology
offers flexible mounting options for various
manufacturing processes. The FARM may be
installed as a conventional leaded device
for on-board applications, in-board for low
profile, height restricted applications,
socketed or surface mounted with optional
ModuMate interconnect products.

PRELIMINARY
Application Note
The Filtered, Autoranging Rectifier Module (FARM) provides an
effective solution for the AC front end of a power supply built
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 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.
In addition to providing transient/surge immunity and EMI
filtering, the FARM 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 only needs to add hold-up capacitors, and
a few discrete components.
3.1 If the bus voltage is greater than 235V as the slope
approaches zero, the inrush limiting thermistor is
bypassed. Below 235V, it is not bypassed.
4.1 The converters are enabled 50 milliseconds after the
thermistor bypass switch is closed.
5.1 Bus-OK is asserted after an additional 50 millisecond
delay to allow the converter outputs to settle within
specification.
Functional Description
Power-Up Sequence. (see Fig. 8):
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
hold-up capacitor value and the thermistor cold resistance.
The slope (dv/dt) of the capacitor voltage versus time
approaches zero as the capacitors become charged to the
peak of the AC line voltage.
Power-Down Sequence. (see Fig. 8) When input power is
turned off or fails, the following sequence occurs as the bus
voltage decays:
1.2 Bus-OK is deasserted when the bus voltage falls below
210Vdc.
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. 7). In addition, the converter modules
are disabled via the Enable (EN) line, and Bus-OK (BOK)
is high.
2.2 The converters are disabled when the bus voltage falls
below 190Vdc. 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, i.e., the power
conversion system “rides through” the momentary
interruption.

Off-Line Power Supply Configuration
The FARM maintains the DC output bus voltage between 250
and 370Vdc over the entire input voltage range, which is
compatible with Vicor 2nd Generation, 300V input converters as
well as 1st Generation VI-26x and VI-J6x DC-DC converters.
The FARM automatically switches to the proper bridge or
doubler mode depending on the input voltage, eliminating the
possibility of damage due to improper line connection. The
FARM1xxx is rated at 500W in the low range (90-132Vac
input), and 750W in the high range (180-264Vac input). The
FARM2xxx is rated for 750W and 1000W 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.
Strap (ST) Pin. In addition to input and output power pin
connections, it is necessary to connect the Strap pin to the center
junction of the series hold-up capacitors (C1, C2, see Fig. 9) for
proper (autoranging) operation. Gas tubes V1 and V2 provide
capacitor protection. The bleeder resistors (R1, R2, see Fig. 9)
discharge the hold-up capacitors when power is switched off.
Capacitors C7 and C8 are recommended if the holdup capacitors
are located more than 3 inches from the FARM output pins.
Enable (EN) Pin. (see Fig. 10) The Enable pin must be
connected to the PC or Gate-In pin of all converter modules to
disable the converters during power-up. Otherwise, the
converters would attempt to start while the hold-up capacitors were
being charged through an unbypassed current limiting 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.
A signal diode should be placed close to and in series with the
PC or (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 400Vdc.
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 180Vdc.

Caution: There is no input to output isolation in the FARM. 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 transformation should be used when performing scope
measurements. Scope probes should never be applied
simultaneously to the input and output as this will destroy the unit.

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 Fig. 13).
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.

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. The ripple rejection (R)
of Vicor converters is specified as a function of the
input/output voltage ratio:
Where:

f = line frequency
θ = rectifier conduction angle

For example, a converter whose output is 15V and nominal
input is 300V will provide 56dB ripple rejection, i.e., 10V p-p
of input ripple will produce 15mV p-p of output ripple
(see Fig. 17). 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. 13) 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:
∆t = (π – θ) / 2πf

Determining Ride-through Time. Figure 15 illustrates ridethrough time as a function of line voltage and output power,

Figure 17—Converter ripple rejection vs. output voltage
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
(7)
Where: P = total output power
Vac = operating line voltage
Determining the Ripple on the Output of the
DC-DC Converter. Figure 17 is used to determine the ripple
rejection of the DC-DC converter and indicates a ripple
rejection of approximately 60 dB for a 12V output. Since the
ripple on the bus voltage is 12Vac 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 12mV p-p.
Note that 2nd Generation converters have greater ripple
rejection then either VI-200s or VI-J00s.

time, ride-through time, and ripple voltage requirements are
given as a function of operating power level in Figures 14, 15,
and 16, respectively.
Example
In this example, the output required from the DC-DC converter
at the point of load is 12Vdc at 320W. Therefore, the output
power from the FARM would be 375W (assuming a converter
efficiency of 85%). The desired hold-up time is 9 ms over an
input range of 90 to 264Vac.
Determining Required Capacitance for Power Fail
Warning. Figure 14 is used to determine 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. Note that warning time is not dependent on
line voltage. A hold-up capacitor calculator is available on the
Vicor website, at vicorpower.com.
