Power Factor Correction Using a Series Active Filter

IEEE Transactions on Power Electronics, 2005
This work presents a low-cost approach to power factor correction (PFC) of single-phase diode rectifiers using a series active filter. Comparing with the traditional PFC, the proposed PFC has lower requirements of power device ratings, which leads to lower cost, higher efficiency, and lower electromagnetic interference.

Power factor correction using a series active filter

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2003
This paper present a low-cost approach to power factor correction (PFC) for single-phase diode rectifiers using a series active filter. Comparing with the traditional PFC, the proposed PFC has lower requirements of power device ratings, which leads to lower cost and higher efficiency, and it also can eliminate the bulky inductor needed in the ...

Saturation influence on the performances of series active power filter

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents a study on the injection transformer, showing the influence of its saturation on the performances of the series active power filter to compensate the voltage perturbation. The determination of voltage references for series active power filter is based on a robust three-phase digital phase locked loop (PLL).

Improvement of Power Quality Using Series Active Power Filter(SAPF)

2020 IEEE International Students' Conference on Electrical,Electronics and Computer Science (SCEECS), 2020
Modern power electronics devices like active power filter and comprehensive simulation study of Relay gives the idea of power quality. Generally, in electrical parallel circuits voltage is constant and current is variable parameter, so by using parallel active filter provided variable currents in system and mainly series active filters are used for ...

Comparison of active power filters with series-connected capacitor

2008 IEEE 2nd International Power and Energy Conference, 2008
In this paper, a method for reducing the voltage stresses on power components and power losses in a shunt voltage source and current source active power filters (VSAPF and CSAPF) is presented. The method is based on series capacitor structure, which is used to block the fundamental supply voltage component.

Design of series active filter for power quality improvement

2014 International Conference on Electronics, Communication and Computational Engineering (ICECCE), 2014
The voltage quality is one of the major concerns for industrial and distribution consumers. In this work, a series active filter for voltage compensation has been verified using vectorial power theory for a three-phase system with non-linear load. The simulation has been designed using MATLAB/Simulink.

Series association of VSI in high power active filtering

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A series association of 'n' voltage source inverters (VSI) used as an active filter is proposed to perform high power filtering. A multilevel working is obtained with shifted control. An original control loop is defined to balance the n VSI capacitor voltages. Experimental results confirm the simulation and valid the theoretical study.

Hybrid series active power filter for mitigating power quality problems

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
This paper presents various power quality problems and its mitigation through a hybrid series active power filter. Series filters have less attention in the power quality area due to its high cost of compensation, bulky transformers etc. Even though hybrid series active power filters are used in three phase system it is less utilized in single phase ...
