Comparative Study of Control strategies for PWM Rectifier Based on PI Controller Applied to Battery Charging

Abstract

"Abstract : In this work, we studied the modeling and simulation of a PWM rectifier connected to a battery, the regulation of the output DC bus voltage using a PI controller, the objective of this work is to reduce harmonic distortions at the input and to obtain sinusoidal input currents with zero consumption of reactive power, which improves the power factor of the power source. The control of the converter is provided by different techniques such as hysteresis and DPC controls. The battery is presented with different models and then connected with a PWM rectifier using DPC control that can be used for a charging system for electric vehicles and renewable energies. Battery performance and characteristics are presented and interpreted for charging and discharging battery cases. The simulation results under Matlab / Simulink show that the PWM rectifier operating at a unit power factor and can provide a stable DC voltage and sinusoidal input currents at with a low THD. "
