A Short Review Paper on Active Filters

Quality of power is related to voltage quality of supply. Voltage quality of supply must be clean i.e. pure sinusoidal waveform of constant frequency 50 Hz in our country. But harmonics are introduced in the system because of non-linear loads. It distorts pure waveform, which affects different equipments differently. This paper presents a review on active filters and its classification. It also explains the effects of harmonics. It gives a little information about components of active filters & control strategy. It concludes with some additional features of using active filter for improvement in power qualityIJSRED-International Journal of Scientific Research and Engineering Developmen
