Abstract

novel high switching frequency isolated voltage- fed (VF) bidirectional dual active bridge (DAB) DC-DC converter with primary triple bridges combining secondary full bridges is proposed for high voltage gain and high voltage interface applications. A novel control method based on the Lagrange Multiplier Method (LMM) with the optimization objective of minimum root-mean-square (RMS) value of the leakage inductor current is subsequently presented to manipulate the converter. The proposed control method contains only a simple control loop and avoids the variable inductance value information and the precise relationship between the control variables. The proposed converter and the control strategy are verified by the simulation.
