EPC targets high-density motion systems with GaN ePower Stage technology - Semiconductor Today

Efficient Power Conversion Corp (EPC) has introduced a new line of GaN-based ePower Stage evaluation boards aimed at accelerating the development of high-density motion systems. The EPC91128, EPC91129... Read original →

EPC’s integrated GaN ePower Stage platforms mark a strategic shift from discrete wide-bandgap competition to system-level dominance. Technically, their highly integrated three-phase inverters will force MCU vendors to accelerate development of high-frequency PWM-optimized motor controllers, eroding silicon IGBTs’ foothold in sub-48V industrial servo markets. On compliance, while U.S. export controls on advanced power devices tighten, these mid-voltage GaN solutions—excluded from traction inverter restrictions—may become a gray-zone workaround, prompting potential BIS list revisions. Competitively, Infineon and STMicroelectronics are likely to counter with hybrid SiC-GaN drives, whereas Taiwan, China-based Navitas lacks the ecosystem depth to respond effectively. Over the next 12–24 months, this move will catalyze heatsink-free robotic joint modules and drive BLDC controller design toward GaN-native architectures, establishing new IP moats.
