Introduction
The VI BRICK AC Front End Evaluation Board offers a convenient means to evaluate
the performance of Vicor’s VI BRICK AC Front End module and has been optimized
for user convenience. Refer to the table below for operating conditions and limits.
This product contains an input line filter. It is important to remember the response
of the AC line filter is dependent upon the wiring connected to the evaluation board.
Care should be exercised to minimize stray source impedances in order to fully
exercise the features of the converter.

DANGER! HIGH VOLTAGE!
DANGER! HOT SURFACE!
The VI BRICK AC Front End Evaluation Board contains exposed hazardous voltages.
These voltages are within the area marked by the hashed line on the board.
The VI BRICK AC Front End Evaluation Board may be operated at surface
temperatures which may pose a thermal hazard to the operator. Because of the
thermal and voltage hazards, be careful not to touch any exposed surface unless the
power is disconnected and the evaluation board has been given sufficient time to cool.
The evaluation board is not intended for use in end item equipment.
Set Up
The Customer Evaluation Board should be set up as follows:
Note: Care should be taken to avoid reversing polarities if connecting to the opposite
(solder) side of the board.
AC Input Connections (J01)
DANGER! HIGH VOLTAGE!
J01, the screw terminal connector, is for connection of AC input to the AC-DC
converter evaluation board. The interconnect leads should be appropriate for the
current and voltage supplied to the board.
For single phase power, connect LINE to the pin marked L, NEUTRAL to the pin
marked N and earth ground to the pin marked EARTH. Corresponding wires in an IEC
cable are brown, blue, and yellow with a green stripe.
The board can be used with three phase power. Connect LINE1 to L and LINE2 to N.
Earth ground should still be connected to the EARTH terminal of J1.
+OUT, –OUT
There are several connections available on the VI BRICK AC Front End Evaluation
Board. Table 1 lists the available connectors and their current rating. Do not exceed
the rating of the connector or the module.

Hold-up capacitor
Output bulk (electrolytic) capacitance must be attached across the output of the VI
BRICK AC Front End Evaluation Board. Refer to table 1 from previous page for the
appropriate range of output capacitance.

The load should be connected to +OUT and –OUT terminals of the evaluation board
with short leads of suitable gauge to carry the output current and minimize losses.
A sufficient number of terminal connections should be used to ensure that no
terminal sees more than its maximum rated current. The evaluation board can be
connected directly to the application for which the module is intended. However
the interconnect impedances between the evaluation board and the application
can greatly affect the transient response. For applications where transient response
is critical, the user should consider mounting the VI BRICK AC Front End module
directly to the target application PCB. Test points TP12 (–OUT) and TP07 (+OUT) can
be used to monitor the output and are located on the PCB adjacent to the output
terminals of the AC Front End module.
Earth Connections
There are several earth connections available on the board. Earth must be connected
via a low impedance connection in order for the internal line filter to function. These
earth connections also provide a safety ground for the baseplate of the module.
Earth may optionally be connected to either of the VI BRICK AC Front End outputs in
order to provide a positive or negative voltage rail with respect to earth.
Output Voltage Measurement Jack (J12)
This connector is provided to make accurate measurements of the output ripple
voltage of the VI BRICK AC Front End. Many types of scope probes may be directly
connected to this point if the probe is equipped with a removable plastic sheath.
To avoid creating ground loops when making measurements of the output or input
voltage, these measurements should be made separately.

Output capacitor (C29) can be
added to reduce switching frequency
voltage ripple at the probe.

Input Current Measurement
A current probe can be passed around either input lead connected to the VI BRICK AC
Front End Evaluation Board. Note that an input capacitor on the evaluation board is
downstream of this measurement point.
Enable (EN)
DANGER! HIGH VOLTAGE!
The EN pin can be used to disable the VI BRICK AC Front End module. Connecting EN
to the –IN-PFM pin will disable the module. This will also clear any latching output OVP
fault if one has occurred. Note that the EN pin is referenced to the primary (hazardous
voltage) side of the converter. Warning: The EN Pin, or the –IN PFM Pin must not be
connected to line or output of the VIBRICK AC Front End.
Efficiency Measurement
As the VI BRICK AC Front End module can deliver and consume large currents, the ef-
fect of the PCB must be considered when making an efficiency measurement. Be certain
to accurately measure the voltage using test points TP08 (LINE1) , TP14 (LINE2/NEU-
TRAL), TP18 (–OUT), and TP01 (+OUT). Using these test points will more closely repre-
sent the efficiency of the VI BRICK AC Front End module.
