   DYNAMIC BEHAVIOUR OF A PARALLEL SINGLE PHASE ACTIVE POWER LINE CONDITIONER
By D. Gonzalez; J. Balcells; A. Arias [View]
[Download]

Abstract: In this paper, the dynamic behaviour of a parallel single phase active power line conditioner (APLC) with different loads is studied . A prototype has been built and experimental results are presented for several types of disturbing loads (controlled and non controlled rectifiers and AC/AC phase controlled couvertes).

   ACTIVE POWER FILTER FOR SUPPRESSION OF LINE CURRENT HARMONICS
By P. Brandstetter; T. Bubela [View]
[Download]

Abstract: This paper presents some results of controlling of the voltage-source active filter for reduction of high harmonics in the supply current. The filter is suitable for symmetrical three phase loads such as rectifier or frequency inverter. Several ways of current flow controlling and regulation of the filter currents are described and experimentally proved. Simulation and practical results showing the dynamic state system's performance are presented.

   A SPACE VECTOR BASED ACTIVE POWER FILTER FOR THE COMPENSATION OF HARMONIC DISTORTION AND FUNDAMENTAL REACTIVE POWER
By A. Dell'Aquila; A. Di Lorenzo; P. Zanchetta [View]
[Download]

Abstract: Active power filters are becoming more and more the better approach for providing the reduction of the "harmonic pollution" produced by non linear loads. In the paper we propose a shunt active power filtering system based on a three phase PWM space vector inverter that allows us to obtain, by means of a fully digital processing control, line currents with very low harmonic distortion together with the possibility of full control of fundamental current phase angle for the contemporaneous compensation of the reactive power. Simulation results show excellent compensation of both harmonic currents and reactive power.

   COMPENSATION OF INFLUENCE OF RECEIVERS ON POWER NETWORK WITH APPLICATION OF POWER ELECTRONIC CURRENT SOURCE
By L. Frackowiak; M. Gwozdz; R. Porada [View]
[Download]

Abstract: The paper shows system achieving optimal compensation in real time by elimination of differential current. For that purpose we applied power electronic controlled current source which preserves linear characteristic in respect to input and output. Also schematic diagram and principle of system work has been presented. Simulation tests were provided for ideal and simulated real current source. The results of simulation indicate to very good reduction of source current distortion in condition of strong distortion of voltage and current of receiver. The obtained results of tests carried out on laboratocy system of current source confirm the results of simulation tests and show high efficiency in realization of assumed objectives.

   A New Configuration for Shunt Active filters
By M. El-Habrouk; M. K. Darwish; P. Mehta [View]
[Download]

Abstract: A new configuration for single-phase shunt active filters, which does not use the standard inverter configuration, is presented in this paper. The proposed circuit offers an easier control technique with smaller component values. The principle of operation is discussed in this paper in addition to the analysis and comparison with the existing techniques.

   IMPROVEMENTS OF PARALLEL ACTIVE POWER FILTER PERFORMANCES
By I. Rasoanarivo; P. Boos; B. Davat [View]
[Download]

Abstract: The advantages of applying active power filters to industrial installations are very well-known. They especially afford easy handling of current harmonic compensation using microprocessors. This study developed a new control strategy based on the use of active power filters to compensate reactive energy as much as possible. Simulation results presented illustrate the good performance of the principle. An industrial device based on the proposed principle is in fact being constructed by the firm SOCOMEC.

   NUMERICAL AND EXPERIMENTAL COMPARATIVE STUDY OF VOLTAGE SOURCE AND CURRENT SOURCE ACTIVE POWER FILTER
By L. Benchaita; A. Salem nia; S. Saadate [View]
[Download]

Abstract: The utilization of active power filters in harmonic compensation has been considerably generalized recently. In our laboratory, different configurations, shunt and series, have been studied and some publications issued. This paper deals with shunt active filters and two structures, voltage source (VSAF) and current source (CSAF), are studied and compared. Firstly, numerical simulation is employed to discuss the following comparison points:
-Power circuit design.
-Semiconductor constraints.
-Filtering quality.
-Robustness and adaptability.
-Load transient regime.
Then the experimental results of voltage source active filter are presented.

   ANALYSIS AND REDUCTION OF COMMON-MODE DISTURBANCES INDUCED BY PWM RECTIFIERS
By P. Thalin; P. Ladoux; J. Nuns [View]
[Download]

Abstract: The rectifiers used in induction heating systems have a poor power factor. Power factor correction of these rectifiers can be achieved by using PWM control. In this paper, the authors show that PWM rectifiers produce common-mode disturbances on the distribution network. Finally, different solutions for reducing these disturbances are proposed and validated by experimental results.
