HARMONIC REDUCTION IN INVERTER WITH DIFFERENT TECHNIQUES INCLUDING FUZZY & PI SYSTEM

Abstract

One of the serious issues in electric power quality is the harmonic substance. There are a few strategies for showing the amount of harmonic substance. The most broadly utilized measure is the total harmonic distortion (THD). Different exchanging methods have been utilized in static converters to diminish the yield harmonic substance. As indicated by the voltage varieties, the exchanging points can be produced from the impedance framework. These exchanging points can make the staggered inverter yield voltage with diminished THD. Harmonics are flows and voltages that are products of crucial frequencies. Regularly they are delegated even and odd harmonics where odd harmonics are typically viewed as deadly for a power framework. This paper clarifies about the different kinds of Harmonic Reduction Techniques in Voltage Source Inverters (VSIs, for example, Active filters, Passive filters and Hybrid filter methods. The different control strategiesare also discussed here. An endeavor is made to recognize a control method which grants higher harmonic reduction inside the AC yield voltage of the inverter.
