الملخص

This paper presents an comparative study between shunt active filter and shunt hybrid filter based on configuration system and harmonic isolation. The harmonic isolator is
based on Self Tuning Filters (STF) (it can be tuned at any frequency). The study of the active filter control is divided in two parts. The first part deals with the harmonic isolator which generates the harmonic reference currents. The second part focuses on the generation of the switching pattern of the IGBTs of the inverter by the modulated hysteresis current controller. The studied hybrid active filter consists of an active filter and three phase tuned LC filters for 7th harmonic frequency. The nonlinear load is a diode rectifier feeding a (R, C) parallel load. The use of STF's simplifies the control scheme by reducing the number of extraction filters. The use of STFs instead of classical extraction filters allows extracting directly the voltage and current fundamental components. The effectiveness of this study has been verified by computer simulation and comparing the results.
