Power Electronics for Electric Vehicles: State-of-the-art and Future Trends

The rapid evolution of electric vehicles (EVs) has significantly increased the demand for efficient, compact, and high-performance power electronic systems. This paper entails an in-depth investigation of the recent developments and future outlook of power electronics in electric vehicles. EVs operation is centered on power electronics that transform, regulate and control electrical power in various subsystems, such as traction inverters, DC-DC converters, onboard and fast chargers, and battery management systems. With the advancement of wide bandgap (WBG) semiconductor technologies like silicon carbide (SiC) and gallium nitride (GaN), EV powertrains have achieved higher efficiency, better thermal performance, and reduced size and weight. In the following paper, the authors will explain the relative advantages of traditional silicon versus WBG materials in power devices and explore how they may affect the design and performance of EVs. Methodologically, the research offers the literature synthesis coupled with simulation-based testing of converter and inverter models, as well as comparison of their performance under critical parameters and its benchmarking. High efficiency and harmonic reductions results are confirmed by SiC and GaN technologies. Furthermore, the study identifies future trends such as the integration of artificial intelligence (AI), modular converter architectures, 800V platforms, and bidirectional charging systems. Such innovations will power the next generation of EVs and contribute to the fact that transportation systems become cleaner and smarter.
