Abstract: Frequent widespread use of power electronics equipment by consumers has led to power quality problems in the power system network, due to their nonlinearity. Due to this problem, the current and voltage waveforms are no longer sinusoidal, resulting in the generation of harmonics. Various methods have been deployed to mitigate harmonic issues, including passive power filters and shunt active power filters. Presently, passive power filters are limited in use because of their demerits, including the production of parallel resonances, being heavy in size, and mitigating only a few harmonics. With the advancement in technology, shunt active power filters have become superior to passive power filters due to their limitations. Shunt active power filters were tested for suppressing harmonics produced by nonlinear loads. This article uses a synchronous reference frame (SRF) in generating harmonics produced by nonlinear loads. However, T2FLC is used to control the DC bus voltage of the filter constant. A hysteresis current controller was introduced to fire the gating signal of the IGBT inverter circuit. MATLAB software was deployed in the simulation work. Results obtained have satisfied the tolerable 2014 revised harmonics limit.
