dc.description.abstract-translatedIn this paper, a new zero voltage transition (ZVT) bridgeless PFC converter with high power factor and high efficiency is presented. The proposed converter has not any extra voltage stresses on semiconductor elements. Main switches of the converter are switched under zero voltage (ZV) condition. Also the auxiliary switch is turned on under zero current (ZC) and turned off under zero voltage and current (ZVZC) condition. Due to use of bridgeless topology and soft switching technique simultaneously the converter's efficiency is higher than conventional counterpart. Also the proposed converter does not need the float gate driver. The operation of proposed converter is analyzed theoretically and the operation modes are presented. The design considerations are explained by a design example. The proposed converter is simulated by PSIM software to show the validity of theoretical analysis. The simulation results are compared with theoretical waveforms. The efficiency of simulation in ORCAD software shows 2% improvement in comparison with conventional PFC boost converter.en
