Classification and Comparison of BPFC Techniques: A Review

Power factor correction (PFC) techniques play an important role in green power and energy-saving technology. Based on conventional boost PFC, many novel topologies and control strategies of bridgeless PFC(BPFC) have been proposed, and BPFC reduces the number of devices, the losses and improves the power density as well. In this paper, it discusses and investigates a variety of low conduction losses and high power factor performance of the BPFC topological structures and identifies their merits and limitations by comparing and analysing bridgeless boost PFC,bridgeless buck PFC ,bridgeless sepic PFC and Bridgeless cuk PFC. And the trends of bridgeless PFC techniques are analyzed in the meantime. For the selection, application, and the later structural optimization of Bridgeless PFC techniques which are used in the smart grid, distributed energy and green power and other equipments.
