The paper presents a modified bridgeless single phase pseudo-boost ac-dc converter which has the merits of less component count, improved thermal management, efficiency and high power density as compared to the existing PFC rectifier. Conduction losses are less as a diode rectifier bridge is absent and a single conducting diode is present in the path of current in every stage of the switching cycle. This topology is basically designed for resonant mode operation. Operating in resonant mode adds merits like zero-current switching along the switches and across diode at the output end. This makes the control circuitry less complex. The converter is analyzed using average current mode control (PI controllers). The simulation is done using PSIM software and from the simulation results it is inferred that the converter works at a raised power factor with high efficiency which best proves its applications in low power supplies. © International Science Press.
