A new soft switching bridgeless PFC converter with lossless snubber [PDF]
2016 International Conference on Applied Electronics (AE), 2016 Increasing use of rectifiers causes harmonics pollution in networks. So use of power factor correction (PFC) in converters is inevitable. For reducing weight and volume of converters, designers try to increase switching frequency. The switching losses and conduction losses are two sources of losses in the switching power converter. Thus to reduce these

A New ZVT Quadratic High Step‐Up Nonisolated DC‐DC Converter
Journal of Engineering, Volume 2025, Issue 1, 2025.This paper introduces a quadratic DC‐DC converter that operates with zero‐voltage transition. In this converter, the combination of integrated coupled inductor technique and diode–capacitor technique is employed to boost static gain and decrease voltage stress on the main switch. Moreover, with the help of a third winding wound on the main ferrite core
