EPC Launches 400W Motor Drive Demo Board

Article By : Efficient Power Conversion Corp.

Efficient Power Conversion's EPC9146 drive demonstration board achieves an efficiency of greater than 98.4% at 400W output power.

Efficient Power Conversion Corp. (EPC) has launched the EPC9146, a 400W motor drive demonstration board that contains three independently controlled half bridge circuits, featuring the EPC2152 monolithic ePower Stage with integrated gate driver, 80V maximum device voltage, and 15A (10ARMS) maximum output current. The inverter board measures just 81x75mm and achieve an efficiency of greater than 98.4% at 400W 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. It 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.

eGaN FETs and integrated circuits provide the fast switching, small size, and low cost needed to further reduce the size and weight of BLDC motors, reduce audible noise, improve torque for faster reaction times, and increase efficiency,” said Alex Lidow, CEO of EPC. “The EPC9146 is an ideal example of the capabilities of the integrated power stage, EPC2152, to expand the application areas that can take advantage of the design simplification and performance improvements that GaN offers.”

EPC is the leader in enhancement mode gallium nitride (eGaN) based power management. eGaN FETs and integrated circuits provide performance many times greater than the best silicon power MOSFETs in applications such as DC-DC converters, remote sensing technology (lidar), motor drives for emobility, robotics, and drones, and low cost satellites.
