Isolated Gate Driver evaluation board for 1200V Dual XT or EconoDUAL IGBT module family.
The customer wanted to add a few more features in addition to the gate driver circuit, such as DC link voltage measurement, power module temperature measurement, and current measurement interface. Our mission was to fit all these components onto a relatively small printed circuit board while meeting all relevant Isolation Coordination Standards.
The Broadcom® EB1200-339J evaluation board features dual-output isolated gate drive ACPL-339J optocouplers, used to drive Dual XT and EconoDUAL IGBT modules, and precision optically isolated ACPL-C87B amplifiers used for DC bus voltage and IGBT temperature measurements. The EB1200-339J can also be used in conjunction with ACPL-736J sigma-delta current sensing module to measure IGBT output current. The EB1200-339J is developed to support Broadcom customers during their first steps in designing inverter applications with ACPL-339J drivers.
