Seven-level shunt active power filter [PDF]

open access: yes2004 11th International Conference on Harmonics and Quality of Power (IEEE Cat. No.04EX951), 2005
In this work, the seven-level cascaded type inverter is used as a shunt active power filter to exploit multilevel inverter advantages. The capacitor voltage control technique used as a harmonic current extraction method for the two-level inverter is extended to the seven-level shunt active power filter.

Shunt active filter for reactive power compensation [PDF]

open access: yesInternational 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

A notch filter based active damping of llcl filter in shunt active power filter [PDF]

open access: yes2017 International Symposium on Power Electronics (Ee), 2017
Shunt Active Power Filter (APF) is a custom power device applied in electric grid system in order to compensate harmonic currents generated by nonlinear loads. Shunt APF operates by firing power electronic devices of voltage source inverter (VSI) to produce the compensation currents. The VSI also generates high frequency switching ripple harmonics that

Application of shunt active power filters in active distribution networks

2022 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2022
Constant increase of electricity demand and integrated renewable energy sources in the grid results in harmonic distortions which can impair power quality (PQ). This paper proposes a methodology for the selection of shunt active power filters as a possible solution to these problems and suggests a way to determine the reference current of the filter ...

Direct power control of shunt active filter

2007 European Conference on Power Electronics and Applications, 2007
This paper presents a new control method entitled direct power control (DPC) for shunt active power filtering, which is applied to eliminate line current harmonics and compensate reactive power. Its main goal is to rebuild active and reactive powers to be compared to references values using hysteresis control.

Shunt active power filter with ADMC330

Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2002
In this paper, we describe a scheme for the shunt active power filter with ADMC330 (single chip DSP microcontroller) which was developed successfully. The results of experiment indicate that harmonic currents in three-phase three-wire system could be compensated successfully.

Adaptive Compensation of Reactive Power with Shunt Active Power Filters

Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006
This paper describes an adaptive method for compensating the reactive power with an active power filter (APF), which is initially rated for mitigation of only the harmonic currents given by a nonlinear industrial load. It is proven that, if the harmonic currents do not load the APF at the rated power, the available power can be used to provide a part ...
