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 flo...
