With the growing use of industrial drives, the problem of injected harmonics becomes critical. These harmonics require the connection of harmonic filter in the network. The filter is design to minimize harmonic distortion caused by source such as drives. several types of passive filters are effective in minimizing voltage distortion caused by non linear loads in industrial power systems .Different alternatives for filter design should be considered before making the final decision on filter configuration. Among the criteria used for performance evaluation are current, and voltage ratings of each of the filter component, and the effect of filter and system contingency conditions .The design and performance of passive filter will be discussed. It will reduce the current and harmonic distortion. The most of power quality problems are caused due to non-linear loads such as induction furnace and use of power electronic device. The non-linear load produces harmonics which destroy the sinusoidal nature of supply. So that it is important to mitigate this harmonics .The best method of mitigating harmonics is by using by filter. The series active filter is suitable for the mitigation of voltage harmonics. In this paper we discussed the control strategies of active filter which mitigate harmonics and maintain waveform sinusoidal.
