Modulation strategy for a Dual Active Bridge converter using Model Predictive Control

Abstract : In order to actively control the power flow in a Dual Active Bridge (DAB) converter, different modulation strategies such as Single Phase Shift (SPS), Triangular Modulation (TRM), Extended Single Phase Shift (ESPS) have been proposed. Each modulation is more suitable for a given range of load power level and has difficulties in working with a wide range of load power level. As these strategies are complementary and their combination can improve the DAB converter yield, in this paper, Finite Control Set Model Predictive Control is used to choose the best modulation strategy at the best moment in order to improve the efficiency of the DAB converter in real time. This choice will be made according to a cost function taking a trade-off of the current across the leakage inductance, the power error and the switching losses.
