EPC Targets High-Density Motion Systems with GaN ePower™ Stage Technology - The National Law Review

On June 3, 2026, Efficient Power Conversion (EPC), a global leader in enhancement-mode gallium nitride (eGaN®) power devices, introduced new EPC91128–EPC91131 evaluation boards designed to accelerate ... Read original →

EPC’s integrated GaN motor drive platforms signal a strategic pivot of wide-bandgap semiconductors from static power conversion into dynamic motion control. By monolithically integrating gate drivers, sensing, and protection into ePower™ Stage ICs, EPC slashes BOM complexity and PCB footprint—forcing MCU vendors like TI and Renesas to open ultra-fast PWM interfaces for high-frequency GaN switching. While the 10–80V range currently avoids U.S.-China export controls, expansion into electric commercial vehicles or defense robotics would trigger stricter supply chain scrutiny. Competitors like Infineon and STMicroelectronics will likely counter with hybrid SiC-GaN modules, whereas Taiwan, China-based firms remain hamstrung by limited native GaN substrate capacity. Within 18 months, this approach will establish 'heatsink-free' as a new benchmark in servo drives and drone ESCs, compelling controller ecosystems to rebuild reference designs around GaN-native architectures.
