Abstract :
Power electronic transformer (PET) has many merits as compared with conventional power transformer. For high-voltage high-power applications, silicon based IGBT and the cascaded modular structure are still the mainstream power semiconductor device and structure, respectively. In this paper, a basic design process of the power stage of an H-bridge based three-stage PET system is presented. Based on the design process, different PET designs based on different voltage rating IGBTs are done and compared. This is a reference for practical PET system design.
