Study on Magnetic Materials Used in Power Transformer and Inductor

摘要: Power electronics system is generally comprised of electrical and magnetic circuits. Nowadays, there were a lot research works on circuit topologies ranging from single switch converter to soft-switching topologies, but the most difficult problems encountered by many design engineers issues, such as construction transformer or inductor, application air-gap, under- over-estimated power rating components, selection core so on. The overall performance any converters depend not only design, also this paper will address some common related applications critical factors involved into development components for converters. A brief summary major materials, soft ferrites, powder iron alloys be mentioned in too.
