Abstract

This paper proposes an optimized extended phase shift modulation (EPSM) for dual active brid ge (DAB) converters in vehicle-mounted battery systems. It analyzes the operational principles a nd power transfer dynamics under EPSM, focusing on dual-phase shift variables (D₁, D₂). A mul ti-objective strategy coordinates zero-voltage switching (ZVS), peak current, and circulating powe r constraints. By dynamically tuning D₁ and D₂ across power levels, the method extends the ZV S range, reduces peak current stress, and minimizes circulating power versus conventional sche mes, while maintaining >95% efficiency under wide voltage/load variations. Simulations validate i ts effectiveness for high-efficiency, bidirectional energy transfer in automotive applications.
