原始语种摘要: In this study, the essential reason for causing the dual-side flow back currents in the isolated dual active bridge (DAB) DC–DC converter is originally revealed first. It is because the polarities of the AC side output voltages of the two H-bridge converters in DAB converter are not able to be always kept the same as that of the inductor current in the conventional modulation strategies. An improved triple-phase-shift (ITPS) control is proposed according to the analysis results to ensure that the dual-side flow back currents are eliminated, and all of the power switches achieve soft switching in the entire power range. The detailed experimental results of the ITPS control validate its validity and feasibility.
