EPC's EPC9193 is a 3-phase BLDC motor drive inverter using the EPC2619 eGaN® FET. The EPC9193 operates with a wide input DC voltage ranging from 14 V and 65 V and has two configurations, a standard unit and a high-current version. The EPC9193KIT standard reference design uses a single FET for each switch position and can deliver up to 30 ARMS maximum output current. A high-current configuration version of the reference design, the EPC9193HCKIT, uses two paralleled FETs per switch position with the ability to deliver up to 60 Apk (42 ARMS) maximum output current.
Major benefits of a GaN-based motor drive are exhibited with these reference design boards, including lower distortion for lower acoustic noise, lower current ripple for reduced magnetic loss, and lower torque ripple for improved precision. The extremely small size of this inverter allows integration into the motor housing resulting in the lowest EMI, highest density, and lowest weight.
