[IEEE PELS Toronto Chapter Seminars] GaN Bidirectional Switches: Enabling the Industrialization of Single-Stage OBCs

Abstract: GaN bidirectional switches (BDS) are opening new possibilities for the development of single-stage onboard chargers (OBCs). This seminar will provide an overview of GaN BDS and their application in single-stage OBC architectures, with particular emphasis on the evolution of OBC topologies, control of single-stage power conversion, and the resulting system-level benefits. Recent industry trends in GaN BDS and single-stage OBC development will also be discussed. The seminar will provide an overview of Infineon GaN Canada's R&D activities and its collaboration with academia, offering a broader perspective on the ongoing development of GaN technologies and their applications. Speaker: Juncheng (Lucas) Lu is Senior Director of Technical Marketing for GaN Automotive at Infineon Technologies in Ottawa, Canada. His career spans power electronics engineering, application engineering, product management, and technical marketing, with a strong focus on GaN power technologies and their applications in high-efficiency and high-power-density power conversion. His technical work covers GaN power devices, EV charging, power converter design, and power modules. He has authored and co-authored >40 technical publications and holds >20 patents in the field of power electronics and GaN technologies.
