This book focus on the high frequency power conversion especially on high-frequency isolated DC-DC and single-stage AC-DC converters. Base on dual active bridge DC-DC conveters, two swiches are replaced by two diodes and this makes the DAB suit for unidirectional power flow applications. The shoot through issue can be avoided, the design can be simplified and the cost can be reduced. Compared with widely used high frequency isolated DC-DC converters operating under unidirectional power flow applications, semi DAB based DC-DC converters can achieve full load operating range ZVS for all switches with relying on auxiliary circuits and ZCS off for diodes. Besides, conversion efficiency can improved and optimized with different working conditions. The Semi DAB can be used for AC-DC power conversion. Although without mandatory inner current tracking loops, natural PFC can be obtained. With the proposed control strategies, ZVS for switches even for no load working condition in facing the variation of instantaneous AC grid voltage can be guaranteed. It presents new high frequency isolated unidirectional DC-DC and single-stage AC-DC topologies, advanced modulation and multimode power control methods to improve the performance of converters.
