Overview
The PFC FrontEnd is an extremely low profile, 1 RU enclosed chassis-mount high
Vout AC FrontEnd that may be used with any Vicor 300 V VI-200/VI-J00 brick, HV BCM converter, or 375 V Maxi, Mini, Micro modules and VIPAC Arrays (see page
13 for connection to module and VIPAC Array drawings) to create a complete, highdensity AC-DC power supply. It can be ordered with output voltage set at 360, 375
or 384 VDC and can provide up to four nonisolated outputs (additional using "Y"
adaptors). Accepting universal input voltages of 85 to 264 Vac, and 100 to 380 Vdc, the
PFC FrontEnd can deliver up to 2,200 W in a package size of 1.72" H (43,6 mm) x 6.4" W
(162,6 mm) x 7" L(177,8 mm).

Mechanical Considerations
The PFC FrontEnd can be mounted on one of three surfaces using standard 8-32 (4 mm)
size screws. Maximum allowable torque is 4.4 in. lbs. and the maximum penetration is
0.16 in. (4 mm).
When selecting a mounting location and orientation, the unit should be positioned so
air flow is not restricted. Maintain a 2" (5,1 cm) minimum clearance at both ends of the
PFC FrontEnd, and route all cables so airflow is not obstructed. The power supply draws
air in at the fan side and exhausts air out the same side. If airflow ducting is used, avoid
sharp turns that could create back pressure. The fans move approximately 20 CFM of air.
Avoid excessive bending of output power cables after they are connected to the output
terminals. For high-current outputs, use cable ties to support heavy cables and minimize
mechanical stress on connectors. Be careful not to short-out to neighboring outputs. The
maximum torque recommended on output nuts is 10 in. lbs.
Avoid applications in which the unit is exposed to excessive shock or vibration levels. In
such applications, a shock absorbing mount design is required.
PFC FrontEnd Do’s and Don’ts
n Always turn the power supply off, before disconnecting input or output wires.
n Do not restrict airflow to the unit. The cooling fan draws air into the unit and forces it out at the output power terminals.
n Run the output (+/–) power cables next to each other to minimize inductance.
n Do not repair or modify the power supply in any manner.
Doing so will void the warranty. Contact Factory.
n Insert proper fault protection at power supply input terminals (i.e., a fuse).
n Use proper size wires to avoid overheating and excessive voltage drop.

Technical Description
The PFC FrontEnd consists of an off-line single phase, power-factor-corrected front end,
EMI filter, cooling fan, customer interface and associated housekeeping circuits.
Input AC mains voltage is applied to a terminal block. The input current is passed
through an EMI filter designed to meet conducted noise limit “A” specifications in FCC
Part 15 and EN55022, Class A.
At start-up, inrush current is limited by a PTC thermistor. The PTC is shunted out
shortly after initial power-up by a DC bus voltage sense circuit driving a relay. After
rectification, the input voltage is put through a boost converter that keeps the AC input
current sinusoidal and synchronized with the input AC voltage (in compliance with EN61000-3-2). The boost converter delivers a regulated input to the hold-up capacitors
and a high voltage backplane.
At initial power-up, the PFC FrontEnd output control lines are disabled to limit the
inrush current and to allow the DC bus potential to settle out to the correct operating
level. A low-power flyback converter operating with PWM current-mode control
converts the high voltage DC bus into regulated low voltage to power the internal
housekeeping circuits and DC cooling fan.
The internal housekeeping Vcc comes up within two seconds after the application of
input power. Once the high voltage bus is within operating limits, the AC Power OK
signal asserts to a TTL "1," indicating the input power is OK, and enables the power
outputs. An auxiliary Vcc output of 5 Vdc sourcing up to 0.3 A is provided for peripheral
use.
An output Enable/Disable function is provided by using an optocoupler to control the
converters that are used in conjunction with the unit. If the Enable/Disable control pin
is pulled low, the optocoupler turns on and disables the downstream module output.
Please note that this does NOT disable the 384 V. The nominal delay associated for a
converter output to come up when measured from release of the Enable/Disable pin is
5-10 ms. The General Shutdown function controls all outputs simultaneously and works

Interface Connections
Chassis Input Power Terminals (MBJ6)
Input AC power is applied through connector MBJ6 using Molex mating connector
39-01-4051. Use 16 AWG wire with socket pin 44476-3112 and crimp tool 11-01-0199.
A fault clearing device, such as a fuse or circuit breaker, with a maximum 12 A rating at
the power supply input is required for safety agency compliance. It should be sized to
handle the start-up inrush current of 2 A at 115 Vac and 5.5 A at 230 Vac.

Output Power Connections (MBJ1 - 4)
Outputs terminate in a Molex connector. These outputs are not isolated.
These four outputs all connect to the common 384 V output bus and provide easy
modular connectivity. They also house four separate control lines that provide disable
and enable for Vicor DC-DC converters connected to the PFC FrontEnd. Upon start-up,
all 4 of these lines are held low to disable the external converters until the PFC FrontEnd
comes up properly. After that, control of this function is handed over to the input lines
E/D 1-4. Please note that any external load, whether a Vicor module or other, must be
disabled during the startup phase.
Individual outputs may be connected to more than one module to form output arrays.
Each control line can enable/disable up to three separate modules. Larger arrays may
be possible through the use of external relays or transistor circuits. Please contact
Applications Engineering for assistance in these cases.
In order to minimize parasitic cable inductance and reduce EMI, the output power
cables should be routed in close proximity to one another, and large current loops
should be avoided. To avoid excessive voltage drop, do not undersize power cables,
especially for high current outputs. Excessive cable inductance coupled with large
capacitive loading can introduce instability in switching power supplies. This problem
can be avoided with proper system design. Consult Vicor's Applications Engineering for
assistance with applications that use long cable lengths and excessive load capacitance.

Over Temperature Protection (J5-2)
The PFC FrontEnd monitors the internal heat-sink temperature to provide several
functions:
n Variable fan speed. Minimum fan speed occurs at 24 C and lower as measured on the heat sink. Maximum fan speed occurs at 70°C and above.
n Over-temperature shutdown. If the heat sink reaches 90°C +/- 5°C the Over-Temp indicator signal (pin 2 on CBJ5), which is normally low, will assert high to indicate
an over-temperature condition. Also, all individual module control lines on MBJ1-4 will go low to disable the output loads. The supply will re-enable when the heat sink temperature drops below approximately 83°C and the over-temperature indicator will reset to a low condition.

AC OK is an active high TTL compatible signal and provides a status indication of the
AC input power. It is on pin J6 and is capable of sinking 16 mA minimum. This signal
switches to a TTL "1" when the high voltage bus exceeds low-line condition during turn-on. Upon loss of input power, the bus voltage will drop, causing the AC OK signal
to go low. A minimum of 3 ms hold-up time is provided for a 1,200 W load following the
loss of the AC OK signal.

Enable/Disable (J5-6 to J5-9)
The Enable/Disable control pins allow connected converter outputs to be sequenced
either on or off. The Enable/Disable pins should be pulled low to less than 1 V with
respect to Signal Ground to disable the outputs. They will source 10 mA maximum.
These pins should be open circuited or allowed to exceed 4.5 V when enabled. Do not
apply more than 5 V to these inputs.
General Shutdown/GSD (J5-10)
The GSD control pin on J5-10 allows simultaneous shutdown of all attached converter
outputs. This pin must be pulled down to less than 0.7 V, and will source 4 mA
maximum to shut down all outputs. The GSD pin should be open circuited or allowed to
