Advancements in Power Electronics and Drive Systems for Electric Vehicle Technologies

Abstract

The global transition toward sustainable transportation has propelled the rapid development of power electronics and drive systems for electric vehicles (EVs). These systems form the backbone of EV performance, governing energy conversion, storage management, and efficient propulsion. This paper explores the technological advancements in inverter design, battery management, and high-efficiency electric drives tailored for EV applications. Special emphasis is given to the role of multi-level inverters, bidirectional DC-DC converters, and advanced motor drive topologies such as permanent magnet synchronous motor (PMSM) and switched reluctance motor (SRM) drives. The paper also evaluates the role of wide bandgap semiconductors (SiC and GaN) in enhancing efficiency, compactness, and reliability of EV power trains. Additionally, intelligent thermal management systems, regenerative braking integration, and vehicle-to-grid (V2G) interfaces are examined as key enablers of EV adoption. A comparison between traditional induction motor drives and emerging motor technologies is presented, highlighting trade-offs in terms of cost, performance, and sustainability. The study concludes by addressing the challenges of scalability, charging infrastructure limitations, and the requirement for standardization across EV platforms.
