Fuzzy Sliding Mode Based Series Hybrid Active Power Filter for Power Quality Enhancement

Abstract EN

This paper contributes an innovative gating signal generation technique based on fuzzy sliding mode pulse width modulation (FSMPWM) with a Series Hybrid Active Power Filter (SEHAPF) for reducing the total harmonic distortion (THD).

Hybrid filters are used for compensating reactive power on the load side and mitigate harmonics for the growth of power quality under variable source and load conditions in the utility system.

The objective of the paper is to eradicate the various power quality (PQ) problems with development in power factor and reducing distortion in transmission and distribution line due to harmonics.

With the implementation of FSMPWM of the proposed filter, the gating pulses are generated by implementing a Mamdani fuzzy rule with sliding surfaces.

For producing a fixed pulse the presented method reduces the chattering reaction by controlling the narrow boundary coating on the sliding surface.

The results of the projected technique are analyzed and compared with the traditional hysteresis band current controller (HCC).

The overall proficiency and results are examined with the help of MATLAB/SIMULINK environment.
