EPC introduces fully configured motor drive inverter reference design

Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA — which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) and integrated circuits for power management applications — has introduced the EPC91200, a fully configured motor drive inverter reference design that is said to deliver exceptional performance and flexibility for a variety of industrial and battery-powered applications.

Optimized for wide voltage ranges and versatility

The EPC91200 is designed for 3-phase brushless DC (BLDC) motor drive applications and features the EPC2305, a 150V 3mΩ RDS(on) GaN FET. The EPC91200 supports wide voltage ranges from 30V to 130V, making it suitable for 80V and 110V battery systems commonly used in industrial automation, agricultural machinery, and material handling equipment such as forklifts.

Highlights include:

  • High current capacity: supports up to 60Apk (40ARMS) maximum output current with a switching frequency of up to 150kHz;
  • Enhanced efficiency: optimized PCB layout and advanced GaN technology reduce resistance and heat generation for improved performance;
  • Integrated features: includes current sensing, voltage monitoring, overcurrent protection, and temperature sensing for robust operation;
  • Compatibility: Works with multiple controller boards from leading manufacturers such as STMicroelectronics, Texas Instruments, and Microchip.

Design benefits

The EPC91200 is said to streamline the development process with features tailored for quick deployment and evaluation. The compact design (130mm x 100mm) includes a pre-configured shaft encoder/Hall sensor interface and supports field-oriented control (FOC) techniques. Engineers can easily measure critical signals and optimize system performance using built-in test points.

“With the EPC91200, we provide engineers a versatile, off-the-shelf motor drive solution, showcasing the efficiency, reliability and adaptability of GaN technology in modern power systems,” says CEO Alex Lidow.

The EPC91200 reference design boards are priced at $780. The EPC2305 is priced at $3.56/each in 3Ku reels. Reference design boards and devices are available for immediate delivery from distributor Digi-Key Corp.
