Abstract

This paper proposes a fuzzy controller applied for controling a shunt active power filter. The converter circuit operation follows the concept of lossless commutation.

In this paper the analysis and simulation results are presented for shunt active power filter, operation with fuzzy controller. The aim of the fuzzy controller is to control the output current of the converter so that the supply current waveform remains the same of voltage waveform despit the load current variation. The control system presents good results in terms of response time and robustenss.
