In this paper three leg Voltage source converter (VSC) based Hybrid Active Power filter (HAPF) is proposed for existing problems of harmonics, reactive power compensation, high total harmonic distortion (THD) and Power factor improvement for three phase non linear loads. In the system, a hybrid active power filters which is the combination of active filter and passive filter. The reference curr...

This paper presents a active filter topology and its control technique. Active power filter topology is the most efficient way to compensate reactive power and lower order harmonics generated by non linear loads. The shunt active power filter was consider to be the most basic configuration for the APF. Different techniques have been applied to obtain a control signal for the active filters. One...

This paper proposes a new method of sliding mode base controller for shunt active power filter to compensate the harmonic currents of a load. In this controller there isn't any need to PI DC voltage controller to regulate the DC capacitor voltage of shunt active power filter. In this method, first the reference currents of shunt active power filter that should be tracked to reduce or eliminate ...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...

DSP-based chromatic dispersion compensation accounts for a large part of the overall power dissipation in fiber-optic receiver ASICs. We have implemented and evaluated compensation filters based different design methods using a MATLAB-based coherent fiber-optic system model in respect to compensation performance, filter length, and fixed-point aspects. Possible power savings when taking into ac...

Harmonic distortion is a form of electrical noise. It is a superposition of signals, which are of multiples of fundamental frequency. Proliferation of large power electronic systems results in increased harmonic distortion. Harmonic distortion results in reduction of power quality and system stability. This paper presents fuzzy control applicable for active power filter for three-phase systems,...
