Chapter 1: About This Document
1.1 Scope and Purpose
This document describes how to use Broadcom
®
EB1200-352J evaluation board in a proper and safe way. The
EB1200-352J evaluation board contains a power integrated module (PIM), which includes a three-phase diode bridge, a
brake-chopper IGBT/diode, and a three-phase IGBT inverter, together with the gate driver circuit and DC bus capacitors.
The voltage rating of the power module is 1200V. The evaluation board features an ACPL-352J isolated gate driver that
drives IGBT switches and an ACPL-C87A isolated amplifier that measures the NTC temperature of the power module. The
evaluation board supports the power integrated module (PIM) FP75R12KT4 and FP50R1200KT4G, but other PIMs with the
same pin layout can be used as well. The integrated DC bus feature enables customers to evaluate the ACPL-352J isolated
gate driver in conditions similar to actual applications, such as an industrial inverter.
The EB1200-352J board is a gate driver evaluation board and it is
not
intended to be used as the continuously operating
inverter or as the part of some other series product. Thus, it is
not
intended to be used for the continuous inverter operation;
it enables customers to evaluate driving and other characteristics of Broadcom's ACPL-352J gate drivers that are aimed for
high-performance power electronics conversion systems. For the short time inverter operation evaluation, additional
heatsinks must be mounted.
The EB1200-352J evaluation board can be either supplied with DC current by accessing DC bus terminals, or with AC
current by using the input rectifier of the power module. In case an AC supply is used, ensure that an additional pre-charge
circuit is added. Line chokes and a filter should also be placed. Additional boards with line input filters can be ordered
separately.
If you need more information on the additional line filter board, or more specific data on the inverter operation evaluation,

1.2 Warnings
The board operates at high voltages. Take special care to avoid the risk of injury and life endangering injuries. Consider, and
take seriously, all of the following safety precautions when operating with this board:
If the board is powered up, do not touch the board, especially exposed metal parts.
Pay attention to the maximum ratings.
Use of a protection cover made of insulating materials is mandatory.
After powering off, wait at least 10 seconds for the DC bus capacitors to discharge, and check the DC bus voltage
before touching the board.
If board is used to drive a continuous load, the power module must be mounted on a heatsink. The board temperature
may rise to high values. Therefore, any contact with the human body must be avoided.
The board does
not
have a pre-charge circuit nor the EMC filter features. Thus, do
not
power-on the board directly from
the three-phase AC grid if those features are not provided externally. For laboratory testing purposes, alternatives might
be the usage of a three-phase autotransformer. Large inrush currents can cause failure and explosion of electrolytic
capacitors, which can cause serious injuries.
It is strongly recommended to place fuses at the input when powering the board.
It is strongly recommended to connect a –DC_BUS terminal to ground prior to applying power to the board.
Whenever a change in the test setup is done (for example, changing the probe position), turn off the DC bus and the
+24V supply to avoid injuries and the destruction of the board.
The board itself does not provide dead-time generation. The recommended minimal dead time is 5 µs.
