EPC91202 – 50 ARMS 3-Phase Motor Drive Inverter
The EPC91202 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC2361 eGaN FET 0.75 mΩ typical RDS(on) 100 V maximum device voltage intended for batteries up to 76 V. The EPC91202 can deliver up to 70 Apk (50 ARMS) maximum output current. The board supports PWM switching frequencies up to 150 kHz in motor drive applications.
The EPC91202 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 EPC91202 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 EPC91202 also ships with one (1) EPC9147E controller board
