GaN Motor Drives: Inside EPC’s EPC91202 High-Performance Inverter

Designing Compact Motor Drives with EPC’s ePower Stage ICs

In this episode of GaN Talk, we dive into EPC’s latest 100 V BLDC motor drive reference designs: EPC91128 [https://epc-co.com/epc/products/evaluation-boards/epc91128-29], EPC91129 [https://epc-co.com/epc/products/evaluation-boards/epc91128-29], EPC91130 [https://epc-co.com/epc/products/evaluation-boards/epc91130-31], and EPC91131 [https://epc-co.com/epc/products/evaluation-boards/epc91130-31], all based on the new EPC23xx ePower Stage IC family. Our guest, Francesco Musumeci, Application Engineer at EPC, explains how these compact boards simplify design while boosting efficiency for applications such as humanoid robotics, drones, and e‑mobility. We explore integration advantages over discrete MOSFET solutions, higher‑frequency GaN switching for quieter, smoother motion, current and voltage sensing and protection, and practical guidance for engineers transitioning from silicon MOSFETs to GaN.

Every Watt Counts: GaN Power Architectures for Space VPX Platforms

In this episode of Gan Talk Podcast, we explore how adaptive computing and GaN-based power architectures are redefining onboard intelligence for next-generation satellites. Collin Schairer, Electronics Engineer at Alpha-Data, join us to discuss how AMD Versal adaptive SoCs, combined with radiation-hardened GaN power solutions from EPC Space [https://epc.space/products/rad-hard-gan-hemts/], enable high-density, high-efficiency compute platforms for harsh orbital environments.

JetFleet’s G18 Platform Showcases the Power Density Advantage of EPC GaN FETs

In a recent episode of the GaN Talk Podcast, Maurizio Di Paolo Emilio explored the JetFleet G18 drone and e-bike platform, showcasing how gallium nitride (GaN) technology enables higher power density and efficiency in electric propulsion. JetFleet founder Jernej Fajdiga described the G18 inverter architecture based on EPC2304 [https://bit.ly/4cu1bDd] GaN FETs and addressed key challenges such as thermal management and current sharing. He also highlighted the benefits of higher switching frequencies, including reduced motor noise and improved efficiency, and outlined future plans to integrate GaN inverters directly into motors for lighter, more compact propulsion systems.

Inside EPC’s Phase 18 GaN Reliability Report

In this episode of GaN Talk Podcast, host Maurizio Di Paolo Emilio speaks with Shengke Zhang, Vice President of Reliability at Efficient Power Conversion (EPC), about the newly released Phase 18 GaN reliability report [https://epc-co.com/epc/design-support/gan-device-reliability/reliability-report-phase-18]. They explore why traditional silicon-style qualification is no longer enough, the importance of test‑to‑fail methodologies, and the critical role of thermo‑mechanical and power‑cycling stress. If you design high‑reliability power systems - from data centers to humanoid robots - this conversation is packed with practical reliability insight.

GaN Motor Drives: Inside EPC’s EPC91202 High-Performance Inverter

In this episode of GaN Talk Podcast, Maurizio Di Paolo Emilio hosts a conversation with Federico Unnia, Applications Engineering Manager at EPC. Together, they explore how GaN power devices are revolutionizing high-performance motor drives. The discussion focuses on the new EPC91202 three-phase BLDC inverter, its high-frequency operation, compact design, thermal and EMI optimization, and integrated sensing - showing how GaN is enabling more efficient, quieter, and smaller systems for robotics, drones, e-mobility, and power tools.
