Abstract: As the energy consumption is steeply increasing globally, alternate methods must be adopted to meet the demands. Also to preserve the conventional resources, energy production by renewable sources such as solar, wind, geothermal, tidal, etc is the need of the hour. Energy generation through solar cells can be largely used. But, the harmonic content in the power generated from the solar panels are seemingly higher than the maximum allowable limits. Harmonics are the deviation in the output value from the actual value, caused due to various phenomenal factors. We have observed that the harmonics in the output power from the photo-voltaic cells is way to larger than the limited value. So, we have proposed a three-phase shunt connected IGBT based detuned filtering system to limit the harmonic levels within the desired values. To reduce the current THD value below the permissible limits as specified by the IEEE standards and also to maintain voltage regulation and power factor correction, as well as to improve the efficiency of the entire system.
