Minimum RMS Current Modulation for Three-Phase Dual-Active-Bridge Converter
Year: 2026
Type: conference-paper
Abstract: This paper presents a closed-form double-phase-shift modulation scheme that minimizes the RMS current of a bidirectional three-phase dual-active-bridge (DAB3) DC-DC converter over a wide operating range. Closed-form expressions for the optimal control parameters are derived, and practical implementation guidelines are provided for direct application. The proposed modulation scheme is analyzed in terms of switching-current conditions and soft-switching capability, and its impact on the medium-frequency transformer is evaluated.
