Compensation Strategies for Shunt Active Power Filter in Single- and Three-Phase Systems: Different Formulation, Comparison and Evaluation

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...

Power Quality Improvement Using Fuzzy Controlled Shunt Active Filter

This paper proposes a new control method of three phase active power filterfor reducing the source current harmonics for nonlinear loads. The control strategy includes the dq transformations and hysteresis technique for current injection. Renewable energy source (solar energy) is used as a backup device for converter. Dc voltage deviations due to harmonic injections are tracked by using proport...

Interval Type-2 Fuzzy Control of Shunt Active Power Filter

This paper proposes a new adaptive control technique for shunt active power filter (SAPF) by applying the interval type-2 fuzzy controller (IT2FC) in the DC voltage outer loop. This adaptive method achieved the main control objectives and compensated the active filter parameters uncertainties besides the unbalanced loads compensation without neutral wire. The interval type-2 fuzzy controller (I...
