To overcome the limitation of voltage regulation in resonant switched capacitor topology and introduce the soft switching characteristics into AC/DC converter, a dual-resonant step-up AC/DC converter based on fixed frequency pulse overlapping modulation is presented in this paper. The voltage regulation is achieved by regulating the overlapping time of the two switching pulses, and the switching frequency can be fixed for simplifying the implementation. The operational principle, voltage gain and power factor correction performance are analyzed in detail. Moreover, a simulation model with 165−265 Vrms input and 400 V/1 kW output is built to verify the above analysis, and a model with closed loop is built to verify the controllability.
