Broadcom ACPL-352J | Demoboard EB1200-352J

Beschreibung

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.
