Analysis of The Single Phase Bridgeless PFC Rectifier With Hybrid Switched Capacitor Cell Operating In DCM

In this work the discontinuous conduction mode (DCM) analysis of the Single Phase Bridgeless Hybrid Switched Capacitor Rectifier is presented. The utilization of the DCM in this converter offers notable benefits such as eliminating the need for a current control loop to achieve a high input power factor (PF) and reducing semiconductor switching losses. The modulation scheme, operational stages, and design equations are presented, along with simulation results for a 240 W converter with an output of 1200 V and an input of 220 V. The specifications employed in this study were selected with the aim of obtaining an initial-stage converter for electroporation application.
