Abstract

For the key equipment in bidirectional power transmission system—dual-active-bridge (DAB) DC-DC converter, this paper first provides an overview of its basic principles and topological structure. Then, the basic modulation strategy of triple-phase-shift(TPS) for DAB converters was introduced, and the mathematical models of the converters under different operating states were further constructed and analyzed. In order to reduce the backflow power of DAB converters under the TPS control while reducing the current stress and thereby improving converter efficiency, this paper optimizes the backflow power under different modes based on the Lagrange multiplier optimization equation with the given power as the constraint condition. Finally, a simulation of the DAB converter is built based on the Simulink module in MATLAB, and the effectiveness of the proposed optimization control strategy is verified through comparison.
