Synthesis of a sliding loss-free resistor based on a semi-bridgeless boost rectifier for power factor correction applications

In this work a Loss-Free Resistor (LFR) based on a semi-bridgeless boost rectifier is synthesized using sliding mode control. A better efficiency can be obtained from bridgeless boost converters because of their reduced conduction losses in comparison the traditional PFC boost converters. Although different bridgeless topologies have been presented, the semi-bridgeless topology presents less common-mode noise and its practical implementation is more suitable. Sliding mode control is proposed to achieve a LFR behaviour and, therefore, its application in power factor correction is possible.
