摘要：

This study is to improve the performance of boost-mode conversion in bidirectional dc/dc converter (bidc/dc), so-called dual active bridge converter (DAB). A current-fed quasi-resonance establishes at the low-voltage side (LVS) of the bi-dc/dc converter and performs by simply adding a capacitor across the LVS DAB. A quasi-sinusoidal energy transfer from LVS to the high-voltage side (HVS) realizes by using a constant-off time control. This approach ensures the switch pair at LVS able to commutate at zero-voltage-switching (ZVS). Modeling and analysis of the current-fed boost conversion conduct in detail. We realize a 1-kW current-fed bi-dc/dc converter in boost-mode conversion to assess the predicted boost-mode performance. The power efficiency as high as about 92% achieves in whole load range.
