Abstract “
Solid state control of ac power using diodes, thyristors and triacs injects the harmonics into the ac mains. These injected harmonics cause low efficiency in the supply system, poor power factor and EMI problems. Active filters have been considered a potential candidate to reduce these problems. This paper deals with an active power-filter (APF) based on simple control with optimum selection of energy storage capacitor. A voltage source inverter with hysteresis current control is employed to form the APF, which uses minimum ....etc

Design and Implementation of Hybrid Active Power Filter



ABSTRACT
This paper deals with a hybrid active power filter
with injection circuit (IHAPF). This paper concluded
that the stability of the IHAPF based on detection
supply current is superior to that of others. To
minimize the capacity of IHAPF, an adaptive fuzzy
dividing frequency-control method,.The generalized
integrator is used for dividing frequency integral
control, while fuzzy arithmetic i ....etc

In this seminar a method for wideband harmonic compensation is presented. The main circuit configuration of the system is shown in Fig. 2. The system compensates the low order harmonics using a simple computational control delay compensation method, while the high order harmonics are filtered with a small passive high pass filter. In the system the whole filtering band of the APF is utilized and the filtering performance is recovered with an HPF when the ability of the APF to filter harmonics effectively is impaired. This way the size of the pa ....etc

ABSTRACT
This paper proposes a shunt active filter to minimize the power quality impact instead of using the conventional fixed Filters of the matrix converters. Matrix converters inject significant harmonics and nonstandard frequency components into power systems. The proposed approach eliminates the total line current harmonics efficiently. By minimizing the Total Harmonic distortion the harmonic pollution in the power system will be reduced, and the power quality will be increased. The proposed approach has been tested and validate ....etc

In this paper, the implementation of a shunt active power filter with a small series reactor for a three-phase system is presented. The system consists of multiple non-linear loads, which are a combination of harmonic current sources and harmonic voltage sources, with significant unbalanced components.The filter consists of a three-phase current-controlled voltage source inverter (CC-VSI) with a filter inductance at the ac output and a dc-bus capacitor. The CC-VSI is operated to directly control the ac grid current to be sinuso ....etc
