EPC9194: 40 ARMS, 3-Phase Motor Drive Inverter

EPC9194 40 ARMS 3-Phase BLDC Motor Drive Inverter
Reference Design Board

EPC9194 Development Kit

The EPC9194 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC2302 eGaN FET 1.8 mΩ maximum RDS(on), 100 V maximum device voltage. The EPC9194 can deliver up to 60 Apk (40 ARMS) steady state output current.

The board can also be configured for multi-phase DC–DC conversion and the EPC2302 supports PWM switching frequencies up to 250 kHz in motor drive applications and 500 kHz in DC-DC applications.

The EPC9194 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 EPC9194KIT includes:

One (1) EPC9194 evaluation board
One (1) EPC9147C controller board
One (1) EPC9147E controller board


  • 3-phase inverter based on EPC2302 eGaN FET with wide input DC voltage ranging from 14 V to 60 V
  • Dimensions: L x W = 130 mm x 10 mm (including connector)
  • Low distortion switching that keeps motor audio emission low and reduces torque ripple
