N2 - In this paper, a bidirectional DC-DC converter is designed and analyzed for On-board charger (OBC) application that requires high power, and wide voltage range. The Dual Active Bridge (DAB) converter is an excellent choice for high-efficiency, high-power density, and bidirectional operation. The rated power of the DAB converter is 11kW and the specified output voltage range is 450V ≤ Vdc ≤ 850V. Hybrid modulation scheme using single-phase-shift (SPS) and dual-phase-shift (DPS) control is proposed to reduce RMS current, conduction losses in the higher voltage level, and achieve zero voltage switching (ZVS)-on of all the switches under wide battery voltage range. ZVS turn-on of all main switches at different voltage gain has been analyzed in detail. The simulation and experiments results are presented in this paper to verify the analysis and design of an 11kW converter prototype operating in the full ZVS range.
