Design and simulation of superior quality input current rectifier based on boost topology

Abstract

This paper deals with an active input power factor correction with single phase bridge rectifier fed boost converter topology using hysteresis current control technique. The duty ratio is obtained by the comparison of a inductor current and a ramp carrier waveform which is associated with hysteresis controller in each switching period. In this work MATLAB/Simulink power system toolbox is used to simulate the proposed system. Simulation results are presented and the improvement in the supply current is illustrated in this work. As the result, the input current waveform is fashioned to strictly sinusoidal and in-phase with supply voltage, entailing high power factor.
