Abstract :
This paper deals with parallel active filtering by means of IGBT-Voltage Source Inverters. The control algorithm is based on the evaluation of active and reactive power by detecting line voltages and load currents. Then these powers are split in their average and alternative components using proper low-pass filters. The features linked to some different techniques of current control are investigated with reference to time behaviour and frequency spectrum of the resultant line current. Simulation results are discussed and compared with reference to a specific case-study.
