A Current Control for Three-Phase Four-Wire Shunt Active Filters
Antonio Dell'Aquila
Agostino Lecci
Abstract
An active filter has been proposed to compensate for harmonic distortion, line neutral current and reactive power in three-phase four-wire systems. The focus is concentrated on current control in order to achieve optimum current tracking by means of fixed frequency driving signals. The effectiveness of proposed control was proved in simulations where the harmonic pollution and imbalance caused by a highly distorting load have been drastically reduced.
