Albuquerque, Friday, 25 July 2025.
EPC Space introduces the EPC7C021, a three-phase motor drive evaluation board featuring radiation-hardened GaN technology, enhancing reliability in aerospace applications exposed to harsh environments.

Revolutionizing Space Applications with GaN Technology

EPC Space has released the EPC7C021, a high-performance three-phase motor drive evaluation board that integrates radiation-hardened gallium nitride (GaN) technology, making it ideal for applications in harsh environments such as space. Officially announced on July 15, 2025, the board aims to enhance the reliability and efficiency of motor drive systems in aviation and aerospace, where robust performance is critical [1][2].

Key Features and Specifications

The EPC7C021 board includes several advanced features such as the EPC7011L7C eGaN IC, renowned for high efficiency, low switching loss, and exceptional radiation tolerance. Each phase of the board utilizes a half-bridge GaN IC, allowing it to deliver up to 6 A at a voltage of 60 V and a maximum drive frequency of 2 MHz [1][3][4]. These characteristics position the product as a key player in advancing technologies for small satellites, ion thrusters, and robotic systems.

Advanced Monitoring and Integration Capabilities

Designed for ease of evaluation, the EPC7C021 not only supports stand-alone operations but can also be paired with the EPC9147A controller daughtercard for closed-loop control. It features comprehensive monitoring and protection measures, including built-in test points, power-good indicators, thermal monitoring connections, and adjustable over-current protection. Additionally, the board supports flexible PWM drive options for seamless integration into existing systems [2][4].

Comparison with Silicon-Based Alternatives

Compared to traditional silicon power MOSFETs, EPC’s GaN technology offers significantly improved performance metrics, including a smaller footprint and faster switching speeds. These benefits cater to an increasing European market demand for high-efficiency solutions in aerospace and automotive sectors, where weight and space are limited resources [1][5]. With its novel features and robust performance, the EPC7C021 sets a new benchmark for motor drive systems subjected to extreme conditions.
