This paper presents a fuzzy logic, PI controlled shunt active power filter used to compensate for harmonic distortion in three-phase systems. The Hybrid active power filter employs a simple method for the calculation of the reference compensation current based on Fast Fourier Transform. The presented Hybrid Active Power filter is able to operate in balanced, load conditions. Classic filters may...

The power quality (PQ) is a major issue for both electrical utilities and their customers. nonlinear loads cause PQ problems like current harmonics, voltage frequency deviation, sag swell. A unified conditioner (UPQC) utilized in this research to minimize these problems. UPQC made up of two active filters (APFs), one which connected the line series other parallel. Unit Vector Template Generatio...

The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective compensation using the newly developed technique of harmonic control arrays. Simulation results confirm the appropriate selective harmonic compensa...

With the significant progress of “coal to electricity” project, electric kiln equipment began be connected distribution network on a large scale, which caused power quality problems such as low voltage, high harmonic distortion rate, and reactive loss. This paper proposes two-stage grid comprehensive resource optimization configuration model. A multi-objective solution based joint simulation pl...

A circuit of a multi-phase active power filter based on multi-stage inverter architecture was introduced. The paper is focused on building the MATLAB / Simulink model of an AC power supply system including a single-phase active power filter with a two-stage inverter. Each stage of the filter uses the pulsewidth modulation (PWM) method. The results confirmed high efficiency of such a compensatin...

A Q-enhanced 8th order CMOS active bandpass filter is presented employing a novel two-stage self-calibration technique. The proposed active filter shows the better out-band attenuation performance than other reported CMOS active bandpass filters. The proposed calibration method enables the stable filtering operation affected by neither the input power variation nor the strong interference power...
