Three Level Inverter Based Shunt Active Power Filter Using Multi-Level Hysteresis Band Current Controller

In this paper, a three-level inverter based Shunt Active Power Filter (SAPF) using Multi-Level Hysteresis Current Controller (MLHCC) is presented for solution of power quality problems in distribution system. A simulation model of SAPF is prepared in Matlab/Simulink environment. MLHCC is used for control of SAPF currents. In simulation study, it is considered that SAPF executes two tasks coveri...

Adaptive Hysteresis Band Based Fuzzy Controlled Shunt Active Power Filter

Conventional hysteresis current controllers have the disadvantage of a variable switching frequency. This paper proposes a fuzzy hysteresis band technique for the current control for shunt active power filter (SAPF). An active harmonic filter is used to eliminate current harmonics caused by nonlinear loads. The current control strategy utilizes using a selective Filter STF method to improve pow...

Hysteresis Control for Current Harmonics Suppression Using Shunt Active Filter

Recently wide spread of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from ac mains. Current harmonics generated by nonlinear loads such as adjustable speed drives, static power supplies and UPS. Thus a perfect compensator is required to avoid the consequences due to...
