Comparative Analysis of Bridgeless, Interleaved and Bridgeless Interleaved Boost PFC using PI and Hysteresis Controller

Abstract

This paper explains about the three different arrangements of chopper for shaping the source current and maintaining in phase relationship between voltage and current using the outer voltage control loop as PI Controller and current control loop in the inner side as Hysteresis Controller. The operation of three topologies is discussed in detail and the comparison table of the closed loop circuits using MATLAB Simulink software in terms of THD, Power factor and efficiency is also presented.
