The DAB converter topology is a promising architecture for its high-efficiency, bidirectional power conversion, galvanic isolation and flexible gating schemes. The primary objective is to evaluate the effectiveness of modulation techniques on output voltage regulation under varying input voltage conditions. Phase displacement patterns and their correlation with the varying input voltage are illustrated graphically along with the detailed results. A comprehensive design analysis is developed, followed by the detailed simulation results is showcased for a 1 kW converter in boost mode of operation. This study highlights the insights for the selection and optimization of modulation strategies for DAB converter in applications demanding precise output voltage regulation and high efficiency. © 2024 IEEE.ModulationSingle Phase ShiftTriple Phase ShiftVoltage RegulationVoltage Variation
