Appendix A. The Novel ZVT and ZCT Soft-Switching Topology

Since the PCS needs to handle high power high voltage, the soft-switching topologies utilized in the design should have both ZVT and ZCT functions. A novel soft-switching topology that has both ZVT and ZCT functions is suggested. The new topology has both ZVT and ZCT functions by using two additional components, a switch and a diode. The auxiliary inductor for soft-switching is implemented inside the main inductor with a tap. This concept can be applied to the isolated converters, the converters for the inductive load, and the three-phase converters/rectifiers.
