A Control Strategy for Bidirectional Isolated 3-Phase Current-Fed Dual Active Bridge Converter
This paper examines the characteristics of the zero voltage switching (ZVS) and zero voltage transition (ZVT) soft-switching applied in the 3-phase current fed dual active bridge (3P-CFDAB) converter, which combines the advantages of the dual active bridge (DAB) converter and current-fed full bridge...
