EPC Space announces GaN-based motor drive board

News
Three-phase drive evaluation board uses radiation-hardened EPC7011L7C eGaN power stage

EPC Space, a maker of radiation-hardened GaN power devices, has announced the EPC7C021, a three-phase motor demonstration board featuring radiation-hardened EPC7011L7C eGaN ICs. Each phase uses a half-bridge GaN IC.

Designed for ease of evaluation and system integration, the EPC7C021 is said to deliver a user friendly, flexible platform for developing motor drive applications such as reaction and momentum wheels, ion thrusters, robotics and other automation in demanding radiation environments.

Measuring 6.50 inches x 5.22 inches, the EPC7C021 can operate as a stand-alone three-phase motor driver or be paired with the EPC9147A controller daughtercard for closed-loop motor control.

The board includes dead-time generation circuitry, current and voltage monitoring, and optional filtering for sine wave approximation—making it suitable for engineers looking to evaluate GaN performance in space- and radiation-critical applications.

“The EPC7C021 helps engineers quickly prototype three-phase motor drives, showcasing the flexibility and monitoring benefits of rad-hard GaN for motor control in harsh environments,” said Maurizio Salato, VP of Engineering at EPC Space.
