Gallium nitride (GaN) technology is rapidly transforming three-phase motor drive systems, especially in applications that demand high efficiency, fast switching, and robust performance in harsh environments such as space. By integrating radiation-hardened GaN ICs into compact, flexible platforms, engineers can accelerate the development and validation of advanced motor control solutions while meeting stringent reliability and size, weight, and power (SWaP) requirements. In this context, the EPC7C021 demo board provides a three-phase motor drive platform based on the radiation-hardened (rad-hard) EPC7011L7C eGaN half-bridge IC, enabling efficient evaluation and prototyping for space-grade motor drive applications. In this article we describe the features, specifications and operating requirements of the EPC7C021, and explain various aspects of how to configure it for different uses. Read the full article at the link below
