Abstract: The performance of Hybrid Active Power Filter (HAPF)for power quality improvement is presented in this paper. Power quality issues are usually caused by nonlinear loads available in the network. HAPF will be a better solution for improving power quality issues. It reduces harmonics, improves power factor and compensates reactive power in the network. Performance benefits of both active filters and passive filters are passive filters are incorporated in HAPF. These filer shave an economical advantage over active filters. Here, the reference current is generated using Synchronous Reference Frame theory (SRF). Fuzzy Logic Controllers (FLC) are used to reduce Total Harmonic Distortion of the source current. The efficiency of Fuzzy Logic Controller based HAPF is evaluated by the simulation implemented in MATLAB/Simulink software.

Keywords: Total Harmonic Distortion, Hybrid Active Power Filter (HAPF), Fuzzy Logic Controller.
