Paper Title
Transformerless Active Power Filter

The purpose of this paper is to give information about a filter which is a collaboration of series and shunt active power filters for achieving the best quality of power without transformer. The obtained model emphasizes on controlling the circulating current in the system. The proposed method utilizes the flexible and adaptive conditioning to reduce all the distortion, hence enhancing and upgrading the quality of power made available to the end users. With the help of pulse width modulation technique it is proved that the enhanced structure has an improved total harmonics distortion than the previous one.
