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.
