EPC Space unveiled the EPC7C021, a high-performance, three-phase motor demonstration board featuring the radiation-hardened EPC7011L7C eGaN® IC.
Designed for ease of evaluation and system integration, the EPC7C021 delivers 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 just 6.50” x 5.22”, the EPC7C021 is a full-featured evaluation board that 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 ideal for engineers looking to evaluate GaN performance in space- and radiation-critical applications.
Key Features of the EPC7C021:
- Powered by EPC7011L7C Rad-Hard GaN ICs: Each phase uses a half-bridge GaN IC delivering high efficiency, low switching loss, and superior radiation tolerance.
- Flexible PWM Drive Options: Input signals can be sourced externally (via SMA or header connectors) or internally from the EPC9147A motor controller board.
- Comprehensive Monitoring and Protection: Built-in test points, power-good indicators, thermal monitoring, and adjustable over-current protection.
- Optional Output Filtering and Thermal Management: User-configurable RC filters for phase outputs and AlN-based thermal “helpers” support higher operating currents.
- Easy Integration: Interface options include Hall-effect sensor input, analog monitoring outputs, and support for external or onboard bias generation (12 V, 5 V, 3.3 V).
