| Abstract |
A reconfigurable series-resonant dual-active-bridge (DAB) converter is proposed for applicationsrequiring wide-range voltage variations such as electric vehicle (EV) chargers. Based on the given outputvoltage range, the proposed converter opts to operate in half-bridge primary and full-bridge secondary (HBFB) mode or half-bridge primary and half-bridge secondary (HBHB). The high-frequency series-resonant LC link is split across the primary and secondary-sides of thetransformer to facilitate dc-offset removal in HBHB mode. An optimal control method is proposed which is applicable to both modes of operations. The effectiveness of the proposed topology and control is validated by experimental results with peak efficiencies of 98.8 \% in HBFB mode and 98.9 \% in HBHB mode. |
