Robust Repetitive Control Design for a Three-Phase Four Wire Shunt Active Power Filter

IEEE Transactions on Industrial Informatics, 2019
This paper presents a discrete repetitive control technique for three-phase four wire (3P4W) shunt active power filter (SAPF). Generally, the control design for power electronics devices involves two control loops: slow acting outer voltage loop and fast

Three‐phase four‐wire shunt active power filter based on the SOGI filter and Lyapunov function for DC bus control

International journal of circuit theory and applications, 2020
The three‐phase four‐wire shunt active power filter (SAPF) was developed to suppress the harmonic currents generated by nonlinear loads, and for the compensation of unbalanced nonlinear load currents, reactive power, and the harmonic neutral current.

Power Quality Improvement using Shunt Active Filter

2017 International Conference on Current Trends in Computer, Electrical, Electronics and Communication (CTCEEC), 2017
In this paper Active filters are used to improve the quality of the power in the load side of the power system. This consists of two parts,1)Simulation in which we are adopting the method of hysteresis control method to reduce the third harmonic at the load side.2)Using a model of MOSFET and gate drivers to minimize the third harmonics at the load side.

Performance enhancement of shunt active power filter with the application of an adaptive controller

IET Generation, Transmission & Distribution, 2020
In this study, an adaptive controller is proposed for shunt active power filter (SAPF) to improve the harmonic compensation performance. The proposed controller forces the source current to become sinusoidal, with less total harmonic distortion and also ...

Shunt active filter for reactive power compensation

International Journal of Electronics, 2001
A simple control technique for three-phase shunt active filters without computation of the reactive current component is presented. A current controller with fast dynamics for an active filter is described. Reactive current is directly controlled without the need for sensing and computing the reactive component of the load current, thus simplifying the

Shunt active power filter synthesizing resistive loads

IEEE Transactions on Power Electronics, 2002
The paper discusses the use of a shunt active power filter to compensate for the line current distortion and to improve the power factor. The advantages of the resistive load synthesis over the sinusoidal current synthesis when the filter is used in a system where the voltage is not perfectly sinusoidal are presented.
