Abstract :
This paper presents the value of completing loss analysis for semiconductor switches in order to maximize the efficiency of any converter topology. A novel constant frequency CLL load resonant converter topology is used as the basis for the presented study. However, the analysis can be extended to other resonant, soft-switched, or hard-switched converters. For the 25 W converter used to present the analysis, it is shown that completing such a study can improve converter efficiency by more than 5%. Comparison between analysis results and switches with the lowest figure of merit (FOM) reveals that analysis is the only way to guarantee the most efficient switches for a given application have been selected
