A double PWM plus double phase shifted (DPDPS) control is proposed for current-fed dual active bridge (DAB) bidirectional DC–DC converters. With which 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 comparison concerning the peak current and RMS current for transformer windings and switches is made by using the conventional PWM plus phase shifted (PPS) control and the proposed DPDPS control. The mode analysis of the proposed control strategy and comparison between PPS control and the proposed control are given. With the proposed DPDPS control, the converter has lower conduction loss, lower peak current, and higher efficiency. A 1 kW prototype is built to verify the proposed topology employing the proposed DPDPS control.
