Abstract In this paper, bidirectional AC-DC converter using dual half-bridge converter is proposed. A transformer leakage inductance in the dual half-bridge converter is used for making resonance with the capacitor of the voltage-doubler, which can help the switched current to be sinusoidal without extra inductive component and also the switching loss can be reduced through operation such as ZVS, ZCS. Both circuit analysis and design guideline are described, and also the feasibility for the proposed converter is shown through the hardware implementation and the experimental results.
