GaN Wine Lounge. GaN stories, insights, and people

GaN Wine Lounge

GaN Wine Lounge is a relaxed video conversation series where we talk GaN - and beyond - with our customers, academic partners, editors, and EPC team members over a virtual glass of wine. In an informal, friendly atmosphere, we share real-world experiences, lessons learned, and fresh ideas. We also include short lab episodes, offering a behind-the-scenes look at experiments and real applications of EPC solutions. Together, we build connections, inspire collaboration, and celebrate the people and technologies shaping the future of GaN.

From Room Temperature to 4 Kelvin: EPC’s GaN Journey for Quantum Computing

Posted Monday, July 27, 2026

This interview with Shengke Zhang, Vice President of Reliability at EPC, explores the development of a fully functional GaN power converter operating at 4 Kelvin. Zhang explains why 4 K is a critical temperature for superconducting and quantum computing research and why GaN HEMTs outperform silicon MOSFETs in cryogenic conditions. He details key engineering challenges, especially wiring and peripherals, and outlines future work on monolithic power stages, system-level reliability for AI, and short-circuit robustness in low-voltage GaN devices.
