Abstract

Notable technological advancements in power electronics have been made in the last years, such as SiC and GaN based transistors. Still, power converters based on these technologies cannot be fully exploited due to passive elements becoming the design bottlenecks at high frequencies. This work analyses the impact of passive components in high frequency power converters, mostly focused in magnetic elements. The necessity of an adequate high frequency design methodology is proved by demonstrating various high frequency effects that are not considered in classical design methodologies. At the same time, a short explanation of different design strategies is made. Lastly, the authors explain the importance of adopting a multi-objective based design methodology for power converters.
