EPC Space, a leader in radiation-hardened (RH) gallium nitride (GaN) power devices, has announced 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 provides a user-friendly, flexible platform for developing motor drive applications, including reaction and momentum wheels, ion thrusters, robotics, and other automation systems in demanding radiation environments.
Measuring just 6.50” x 5.22”, the EPC7C021 is a full-featured evaluation board that can operate as a standalone three-phase motor driver or be paired with the EPC9147A controller daughter card 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).
“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.
The EPC7C021 is available now through EPC Space and authorized distributors.
