N2 - This paper proposes a new interleaved single-stage ac-dc converter that can achieve power factor correction without input current sensing. The converter use a bridgeless structure that can operate in CCM without reverse recovery issue. All switches achieve ZVS turn-on and all diodes achieve ZCS turn-off, which are maintained throughout the whole grid cycle. A SDAB-based modulation strategy is applied which result in simple power control, switching ripple-free input current, open-loop PFC operation and wide-range of output voltage. Experimental results from a proof of concept 2.5-kW, 220Vac, and 200Vdc-350Vdc prototype are given to verify the working principle and feature of the proposed converter.
