Comparison between Two Compensation Current Control Methods of Shunt Active Power filter

摘要: This paper presents the analysis and simulation using Matlab/Simulink of a Shunt Active Power Filter (SAPF) for reducing harmonics current generated by nonlinear loads also compared two control method. Due to increasing usage power electronics equipment with linear load, increase disturbance in ac mains currents has became major concern due adverse effects on all mostly capacitors, transformers, motors, causing additional losses, overloading, malfunctioning overheating interferences. filter is used compensating harmonic non- injecting equal but opposite which gives pure sinusoidal wave.
