400 W Motor Drive Demonstration Powered by GaN Power Stage


The EPC2152 ePower Stage enables higher performance and smaller solution size for high performance, low-cost BLDC motors....

EPC announces the availability of the EPC9146, a 400 W motor drive demonstration. The EPC9146 power board contains three independently controlled half bridge circuits, featuring the EPC2152 monolithic ePower Stage with integrated gate driver, 80 V maximum device voltage, 15 A (10 ARMS) maximum output current. The inverter board measures just 81 mm x 75 mm and achieve an efficiency of greater than 98.4% at 400 W output power.

The EPC9146 can be paired with individually designed mating boards allowing the user to control the power board directly through various mainstream microcontroller boards leveraging existing resources for quick development.  The EPC9146 can be configured to support multiple applications including three-phase motor drives for robotics, drones, e-bikes, e-scooters, multiphase interleaving buck converters, and full-bridge converters.

Price and Availability

The EPC9146 demonstration board is priced at $326.52 each.

The EPC9146KITA which also includes the microcontroller mating board featuring Microchip’s dsPIC33EP- MC digital signal controller (DSC) is priced at $555.98 each.

Both options are available for immediate delivery from Digi-Key.
