Digital controller for reactive power compensation and harmonic current mitigation in single phase Self Excited Asynchronous Generator

This paper presents a Digital controller for Reactive power compensation and harmonic current mitigation in Single phase Asynchronous Generator (SEAG). A digital switching based scheme is used for controller. It consists of 4 four IGBT switches with anti parallel diodes, one capacitor and an AC inductor. The scheme is capable of supplying reactive power for voltage control as per requirements of the Single phase Asynchronous Generator (SEAG) and varying loads. It also supplies required harmonic currents to the nonlinear loads.
