Nowadays, the rapid growth of power electronics in industry and the presence of products based on electronic components in enterprises, institutions, shops, small businesses, residences, etc. and transport systems has been welcomed by the people who already use it due to its increased productivity within all areas. The problem of this increasing use of power electronics equipment is the important distortions originated; the perfect AC power systems are a pure sinusoidal wave, both voltage and current, but the ever-increasing existence of non-linear loads modify the characteristics of voltage and current from the ideal sinusoidal wave
