Abstract
Valley switching technique can reduce the turn-on switching losses in flyback topology by discharging the MOSFET capacitor before the switch is turned on. In this paper, valley switching technique is applied to single-stage power factor correction (PFC) converters to achieve improved performance. Detailed operation principle, simulation results and experimental data are included.
