“…Thus, the proposed FC has better dynamic behavior than conventional PI control. It is claimed [6][7][8] that the fuzzy logic control yields the results, which are superior to those, obtained with the conventional controllers. In the FC, the simplicity of a PI controller is combined with the intelligence and adaptiveness of the fuzzy logic based control system.…”

Abstract: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, which are comprised of nonlinear loads. The active filter is based on a three-phase inverter with six controllable switches. The AC side of the inverter is connected in parallel with the other nonlinear loads through a filter inductance. The DC side of the inverter is connected to a filter capacitor. The Fuzzy Controller (FC) is used to shape the current through the filter inductor such that the line current is in phase with and of the same shape as the input voltage. The results of the computer simulation prove that the injected harmonics are greatly reduced, system efficiency and power factor are improved.

“…Later, they were developed to compensate wider targets like the reactive and unbalance components, receiving then the denomination of Active Power Line Conditioner, APLC [1]. Although, the emphasis must be focused in the Unified Power Quality Conditioners, UPQC [2][3][4][5][6][7][8], which integrate in one module a combination of series and parallel APFs. Both converters are necessary because of the exposed reasons in the last paragraph, for a complete and generic load conditioning.…”

Abstract. This paper presents the obtained experimental results with a single-phase experimental prototype of a Load Compensation Active Conditioner, sLCAC. The sLCAC is composed by a series -parallel combination of active power filters, and its main objective is the global conditioning of a load against harmonic distortion. On the one hand, to isolate the load voltage v L from the harmonics in the supply voltage v S , as well as to regulate it to the nominal value. On the other hand, to improve the supply current i S , compensating the harmonic and reactive components of the load current i L . An experimental prototype has been implemented, and the obtained results are presented to support the performance of the proposed design.

“…Nowadays, PWM rectifiers have been widely applied in series of industrial fields, such as Static Reactive Power Generator (SVG), Active Power Filter (APF), Unified Power Flow Controller (UPFC), High Voltage DC Transmission (HVDC) and some renewable energy generation system [1][2][3][4][5][6]. The key issues concerning the control of a threelevel voltage source PWM rectifier are about neutral potential balancing, switch losses and the cross-coupling between i d and i q .…”

-Three-level PWM rectifiers applied in medium voltage applications usually operate at low switching frequency to keep the dynamic losses under permitted level. However, low switching frequency brings a heavy cross-coupling between the current components i d and i q with a poor dynamic system performance and a harmonic distortion in the grid-connecting current. To overcome these problems, a mathematical model based on complex variables of the three-level voltage source PWM rectifier is firstly established, and the reasons of above issues resulted from low switching frequency have been analyzed using modern control theory. Then, a novel control strategy suitable for the current decoupling control based on the complex variables for i d and i q is designed here. The comparisons between this kind of control strategy and the normal PI method have been carried out. MATLAB and experimental results are given in detail.
