Abstract

Dual Active Bridge (DAB) converters are pivotal in renewable energy, electric vehicles, and energy storage systems due to bidirectional power transfer, galvanic isolation, and zero-voltage switching capabilities. While Silicon Carbide (SiC) devices enhance efficiency through reduced conduction losses and high-frequency operation, conventional SinglePhase-Shift (SPS) control under non-unity voltage ratios induces excessive circulating power and current stress, degrading system efficiency and reliability. The Brayton-Moser (BM) form provides a powerful nonlinear control method through energy-based port Hamiltonian system modeling. To address the aforementioned issues, this study proposes an enhanced Brayton-Moser theory-based nonlinear control strategy integrated with Dual-Phase-Shift (DPS) modulation and minimum circulating power optimization. To enhance system performance under passive conditions and optimize efficiency, a Brayton-Moser theory-guided DAB-based DC power conversion system has been architected and experimentally substantiated via simulation platforms.
