Abstract

A double PWM plus double phase shift (DPDPS) control with equal duty cycles is proposed for current-fed dualactive bridge (DAB) bidirectional DC-DC converters with low and wide voltage range. With these, the circulating current during the non-power transfer stage can be minimized. The mode analysis of the current-fed bidirectional DC-DC converter using the proposed control strategy is given. The root-mean-square (rms) leakage current can be reduced significantly by using the proposed DPDPS control. The ZVS and ZCS conditions for the power switches are given. The converter with the proposed control has lower conduction loss, lower peak current and higher efficiency. A 1kw prototype is built to verify the proposed topology employing the proposed DPDPS control.
