Performance Analysis of Interleaved Single-Phase Rectifier Using Different Current Control Methods

Abstract

In this study, a comprehensive performance analysis of power factor correction control methods are presented for an interleaved single-phase rectifier operating under continuous conduction mode. The control of interleaved converter is achieved using proportional-integral control, average sliding control and predictive current control methods to obtain unity power factor and lower total harmonic distortion of input current. The interleaved power factor correction converters have many advantages in increasing power density, reducing input current ripple and RMS current of the boost capacitor, reducing filter volume, and cutting down the cost of materials. The analysis of the interleaved converter is presented and verified exactly by simulations and experimental carried out on 1 kW power and 50 kHz switching frequency. The performance of the current control methods for the interleaved converter is investigated by Matlab/Simulink program for different cases of operation such as change in input voltage and load. It is observed from the analysis that predictive current control method is more suitable than the others because it doesn't need sense current.
