Abstract

In this paper, closed-loop control of isolated bidirectional dual-active bridge (DAB) DC-DC converter is proposed for dual-phase-shift (DPS) scheme using fixed frequency pulse-width-modulation (PWM) plus transmitted command power. DPS is a well-known control scheme to reduce backflow power, current stress, and losses, it also provides better power transfer flexibility under high frequency. However, the conventional DPS scheme has limited performance in light load conditions. The discussed control technique overcomes the instant variation of inner phase shift ratio (D1) w.r.t outer phase shift ratio (D2) during light load conditions. The theoretical concepts of the transmitted power in different modes of operation are presented in this paper along with a detailed analysis of MATLAB simulation results in dynamic conditions and both directions of power flow. The implemented control scheme leverages most of the improved features of the DPS scheme to transfer power from one end to another end.
