Product Highlights
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 500/750 W or
750/1000 W 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 300 V 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 onboard applications, inboard for low
profile, height restricted applications,
socketed or surface mounted with optional
ModuMate interconnect products.

The Filtered, Autoranging Rectifier Module (FARM) provides an
effective solution for the AC frontend 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.
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.
Functional Description
Initial Condition
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.
Power Up Sequence. (see Fig. 8):
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.
If the bus voltage is greater than 200 V, the doubler is
not activated.
If the bus voltage is greater than 235 V as the slope
approaches zero, the inrush limiting thermistor is
bypassed. Below 235 V, it is not bypassed.
The converters are enabled ~150 milliseconds
after the thermistor bypass switch is closed.
Bus-OK is asserted after an additional ~150 millisecond
delay to allow the converter outputs to settle within
specification.
Power Down Sequence. (see Fig. 8) When input power is
turned off or fails, the following sequence occurs as the bus
voltage decays:
Bus-OK is de-asserted when the bus voltage falls below
205 Vdc (Typical).
The converters are disabled when the bus voltage
falls below 190 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 re-established 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.

Figure 9 —Offline Power Supply Configuration
OffLine Power Supply Configuration
The FARM maintains the DC output bus voltage between 250
and 370 Vdc over the entire input voltage range, which is
compatible with Vicor 300 V input 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 500 W in the low range (90-132 Vac input), and
750 W in the high range (180-264 Vac input). The FARM2xxx
is rated for 750 W and 1000 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.
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. Metal oxide varistors, 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
hold-up capacitors are located more than 3 inches (75 mm)
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 15 V through a 150 kΩresistor.
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 (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 FARM, hence the –Out of the FARM 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.

Bus-OK (BOK) Pin. (see Fig. 11) The Bus-OK pin is
intended to provide early-warning power fail information and
is also referenced to the negative output pin.
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
transformer should be used when performing
scope measurements. Scope probes should never
be applied simultaneously to the input and output
as this will damage the module.
Filter. (see Fig. 12) An integral input filter consists of a
common mode choke and Y rated capacitors (line-ground)
plus two X rated capacitors (line-line). This filter
configuration provides common mode and differential mode
insertion loss in the frequency range between 100 kHz and
30 MHz as illustrated in Figure 6.
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 shut down.
The energy stored on a capacitor which has been charged to
voltage V is:
ε= 1/2(CV2) (1)
Where: ε= stored energy
C = capacitance
V = voltage across the capacitor
Energy is given up by the capacitors as they are discharged by
the converters. The energy expended
(the power-time product) is:
ε= PΔt = C(V12–V22) / 2 (2)
Where: P = operating power
Δt = discharge interval
V1= capacitor voltage at the beginning
of Δt
V2= capacitor voltage at the end of Δt
Rearranging Equation 2 to solve for the required capacitance:
C = 2PΔt / (V12–V22) (3)

The power fail warning time (Δt) is defined as the interval
between B OK and converter shut down (EN) as illustrated
in Fig. 13. 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:
C = 2PΔt / (2052– 1902)
C = 2PΔt / (5,925)
It should be noted that the series combination (C1, C2, see
Fig. 9) requires each capacitor to be twice the calculated
value, but the required voltage rating of each capacitor 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 approximately 56 dB ripple
rejection, i.e., 10 V p-p of input ripple will produce 15 mV
p-p of output ripple (see Fig. 17). Equation 3 is again used
to determine the required capacitance. In this case, V1and
V2are 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
(Δt) between peaks of the rectified line as given by:
Δt = (π – θ) / 2πf (4)
Where: f = line frequency
θ= rectifier conduction angle
The approximate conduction angle is given by:
θ= Cos-1(V2/V1)(5)
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 (6)
Where: P = total output power
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 14,
15, and 16, respectively.
APPLICATION NOTE (CONT.)
Example
In this example, the output required from the DC-DC converter
at the point of load is 12 Vdc at 320 W. Therefore, the output
power from the FARM 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. 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
www.vicorpower.com/powerbench/product-calculators.
Determining Ride-through Time. Figure 15 illustrates ride-
through time as a function of line voltage and output power,
and shows that at a nominal line of 90 Vac, ride-through
would be 68 ms. Ride-through time is a function of line
voltage.
Determining Ripple Voltage on the Hold-up Capacitors.
Figure 16 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 V p-p.
Determining the Ripple on the Output of the DC-DC
Converter. Figure 17 is used to determine the approximate
ripple rejection of the DC-DC converter and indicates a ripple
rejection of approximately 60 dB for a 12 V output. Since 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.
