Real time digital simulation of shunt active filter for mitigation of current harmonics with P-Q theory

The main objective of this paper is to develop PI and Fuzzy logic controllers to analyze the performance of instantaneous active and reactive power (p-q) control strategy for extracting reference currents of shunt active filters under balanced, un-balanced and balanced non-sinusoidal conditions. When the supply voltages are balanced and sinusoidal, then all controllers converge to the same compensation characteristics....
