Compact motor drives and converters enable humanoids, drones and battery-powered tools. High power density DCDC converters from 800 V to point-of-load use EPC’s latest-generation GaN devices.

EL SEGUNDO, Calif. - May 13, 2026 — Efficient Power Conversion (EPC), the world’s leader in enhancement-mode gallium nitride (GaN)–based power solutions, will showcase the company’s newest generation GaN technology for humanoid robotics, drones and compact electrified motion systems at PCIM Europe 2026, taking place June 9-11, 2026 in Nuremberg, Germany, Hall 9, Stand 304. At the show, EPC will demonstrate how its Gen 7 GaN platform enables compact, production-ready power architectures for next generation intelligent motion systems and AI power delivery. These devices offer higher switching frequency, lower losses and tighter layouts - improving efficiency and integration in robotic motion control.

At Efficient Power Conversion, we’re pioneering new frontiers in power electronics with eGaN technology that allows for smaller, faster, more efficient systems. From robotics and drones to AI and Space, EPC helps engineers simplify design and bring next-generation innovations to life.

Over the last few years, there has been phenomenal growth in the adoption of wide-bandgap semiconductors, in what seems to be a consolidated trend toward replacing legacy silicon products. Whereas silicon carbide has successfully targeted electric vehicles and charging infrastructure, gallium nitride (GaN) HEMTs have initially made inroads into consumer-oriented applications, primarily chargers and adaptors. Yet GaN is much more versatile than a simple MOSFET replacement for making chargers slimmer and lighter would suggest.

The EPC33110 is a three-phase module that utilizes gallium nitride (GaN) monolithic integrated circuits, enabling the development of smaller, lighter motor drive inverters. Its compact design is ideal for drone and humanoid robot applications, supporting higher switching frequencies with respect to traditional silicon-based inverters, ultimately improving system size, weight, and performance.
