EPC Space has introduced two new evaluation boards designed to demonstrate high-frequency GaN power conversion in demanding applications such as aerospace, motor drives, and point-of-load (POL) converters.
The newly launched EPC7C010 and EPC7C011 boards are half-bridge power stages configured as buck converters. The EPC7C010 supports 100 V / 20 A operation, while the EPC7C011 targets higher voltage applications at 200 V / 10 A. Both platforms utilize EPC’s eGaN HEMT technology—specifically the EPC7004B and EPC7007B devices—paired with isolated gate driver modules.
Performance-wise, the boards demonstrate strong efficiency levels, with peak efficiency reaching 94.7% for the 100 V platform and 96.6% for the 200 V version. They are optimized for 350 kHz operation but can scale across a wide switching frequency range from 50 kHz to 1.5 MHz, enabling flexibility in design trade-offs between efficiency, size, and thermal performance.
The boards also integrate features such as adjustable dead-time control, galvanic isolation for balanced switching, and configurable output filtering, allowing engineers to tailor performance to specific application requirements.
From a market and technology perspective, these evaluation platforms highlight the continued push of GaN into high-reliability segments traditionally dominated by silicon and SiC. By enabling high-frequency operation with strong efficiency, EPC Space is targeting applications where size, weight, and performance are critical—particularly in aerospace and defense systems.
This release reinforces the broader trend of GaN adoption moving beyond consumer and data center markets into mission-critical environments, where reliability validation and system-level integration tools are essential for accelerating design cycles.
