Magnetics play a pivotal role in power electronics systems, enabling efficient energy conversion, isolation, and filtering. The design of magnetic components such as transformers and inductors determines power density, efficiency, and thermal performance in modern power converters. With the growing demand for high-frequency, high-power-density applications in renewable energy systems, electric vehicles, and smart grids, advanced magnetic design methodologies are essential. This session focuses on emerging techniques in material selection, core design, winding strategies, thermal management, and modeling approaches that improve performance and reliability of magnetic components in power converters.
