In this paper, a new Power Factor Correction controlling technique using bridgeless SEPIC (single-ended primary induction) AC-DC converter with fuzzy control is proposed. The converter design has single switching device of MOFET, to reduce switching losses. This design also has Voltage and Current loop controlling technique to improve the Power Factor and output Voltage. Fuzzy logic controllersetup...
In this paper, a new bridgeless AC-DC single-ended primary induction (SEPIC) converter for power factor correction (PFC) is proposed. The proposed single phase rectifier has 2 bidirectional switch and 2 fast diodes. The output voltage depends on the switching frequency of the MOSFET. This converter produces low conduction loss, low total harmonic reduction and high power factor reaching near-unity...
