<br/><br/> Power system harmonics are considered the major effects on reducing power quality level. So, we must improve these harmonics to acceptable level according to IEEE Std. 519-1992. Usage of some of non-linear loads can produce harmonics in power system networks. In this thesis we have studied two types of non-linear loads which can produce harmonics
