dc.description.abstractA new topology of single-phase SEPIC (Single Ended Primary Inductor Converter) AC-DC converter with low input current THD and high input power factor is proposed. Instead of using a single phase rectifier followed by a boost DCDC converter, or using a bridge rectifier with two diodes and two switches, the rectifier's input is chopped at high frequency during positive and negative cycles by a single bi-directional switch to get step-up/step-down AC-DC conversion. Total Harmonic Distortion (THD) of the input current of the proposed circuit with small input current filter is low. Input power factor and the efficiency of conversion of the circuit are high. No additional control is required to achieve the advantages.en_US
