EPC91200 – 40 A_RMS 3-Phase Motor Drive Inverter

The EPC91200 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC2305 eGaN FET 3 mΩ maximum R_DS(on) 150 V maximum device voltage intended for 96 V batteries. The EPC91200 can deliver up to 60 Apk (40 ARMS) maximum output current. The board supports PWM switching frequencies up to 150 kHz in motor drive applications.

The EPC91200 contains all the necessary critical functions circuits to support a complete motor drive inverter including gate drivers, regulated auxiliary power rails for housekeeping supplies, voltage, and temperature sense, accurate current sense, and protection functions.

The EPC91200 mates with an assortment of compatible controllers, supported by various manufacturers leveraging existing resources for quick development purposes, that can quickly be configured as a motor drive inverter.

The EPC91200 also ships with one (1) EPC9147E controller board
