EPC Releases 5kW GaN 3-Phase Inverters for Robotics and Light EVs

Why It Matters

GaN inverters dramatically improve power density and efficiency, accelerating development cycles for next‑generation motion‑control products in robotics and light‑weight EV markets.

Key Takeaways

• EPC9186HC2/HC3 handle 150 A RMS phase currents
• Switching frequencies reach 120 kHz for fast response
• Parallel GaN FETs cut on‑resistance, raising efficiency
• Boards integrate gate drivers, current sensing, and protection

Pulse Analysis

Gallium‑nitride (GaN) technology is reshaping power electronics by offering lower losses and higher switching speeds than traditional silicon. EPC’s new 5 kW inverter platforms capitalize on these benefits, providing engineers with a compact, high‑efficiency solution for demanding motion‑control applications. By leveraging the EPC2361 eGaN FETs, the boards achieve a 6 V/ns dv/dt rate, which translates into reduced torque ripple and quieter operation—critical factors for precision robotics and lightweight electric vehicles.

From a technical standpoint, the EPC9186HC2 and EPC9186HC3 differentiate themselves through parallel FET configurations. The HC2 pairs two GaN devices per switch, while the HC3 stacks three, effectively lowering equivalent on‑resistance and sustaining higher load currents without overheating. This architecture, combined with a 120 kHz PWM capability and 150 A RMS phase‑current rating, enables designers to push motor performance while keeping passive component size and system weight to a minimum. Integrated features such as high‑bandwidth current sensing and field‑oriented control support simplify the implementation of advanced drive algorithms across a range of controller ecosystems, including Microchip, TI, and ST platforms.

The market impact of these evaluation boards extends beyond immediate performance gains. At a price point of $1 080, EPC lowers the barrier for rapid prototyping, allowing OEMs and startups to validate GaN‑based drive concepts without extensive custom hardware development. Immediate availability through major distributors accelerates time‑to‑market for robotics firms, e‑scooter manufacturers, and drone developers seeking higher power density and quieter operation. As regulatory pressures push for more efficient electrified transport, EPC’s GaN inverters position the company as a key enabler of the next wave of sustainable mobility solutions.
