Design and simulation of active PFC using boost converter used in Marx’s generator

This paper introduces a single stage active PFC AC-DC converter that attains an efficiency of 89% when Vin=85V & efficiency of 98% when Vin=264V. To keep output DC voltage constant, a single-phase diode bridge rectifier is used along with output capacitor of appropriate capacity, calculations for these are given in this paper. Active PFC is considered in this paper due to its wide range of operation, better load handling capability, and higher efficiency. Infineon designer – online spice simulator has been used for modeling and simulation for PFC taking 4KW system.
