Abstract

The main objective of the study is to analysis and design parallel boost power converter for power factor correction using an active filtering approach by implementing single-phase soft-switching technique with an active snubber circuit. Zero voltage transition to turn ON and zero current transition to turn OFF is implemented by the active snubber circuit for the main switches with no any further current or voltage strains. By zero-current switching without the need of added voltage stress, auxiliary switch is turned ON and OFF. The proposed converter has simple structure, low cost and ease of control. The efficiency, which is about 96% in hard switching, will increases to about 98% in the proposed soft-switching parallel boost converter.
