	A STUDY OF PARALLEL CONNECTED DC ACTIVE FILTER FOR LARGE CURRENT POWER SUPPLIES EXCITING SUPERCONDUCTING COILS OF FUSION TEST FACILITY   By Hirotaka CHIKARAISHI; Yuji YONENGA	[View]   [Download]
Abstract: In National Institute for Fusion Science, a helical type fusion test facility (LHD) is now under constructing. This device has 12 large scale superconducting coils driven by thyristor rectifiers. This paper shows a study of de active filter that suppresses the output voltage ripple with small capacity PWM converters connected parallel to these rectifiers.
	Third Harmonic Current Compensator applicable for large office buildings   By J.B. Woudstra; S.W.H. de Haan; P.C. van der Sluijs	[View]   [Download]
Abstract: The diode rectifier and capacitor in the input stage of power supplies of workstations, personal computers, printers, etc. generate harmonics. When used in large numbers, like in large offices, then the third harmonic current component can lead to overload of the neutral line of the three phase power supply. Trondheim A new method of active filtering to eliminate the third harmonic in a supply phase of the grid will be introduced. The circuit consist of a controllable resonant circuit that produces a third harmonic current with the same amplitude as the third harmonic generated by the load. The power circuit and the methods of control are described. In addition both simulated and experimental results will be shown.
	ACTIVE FILTER REFERENCE CURRENT ACQUISITION IN DISTORTED 3-PHASE SUPPLY SYSTEMS   By Chee W. Lu; Alasdair C. Renfrew	[View]   [Download]
Abstract: In this paper, new shunt active filter control methods to obtain the reference currents under distorted 3-phase supply system conditions are presented. The implementation of conventional instantaneous power theory introduces substantial distortion in the reference current template which results in significant supply harmonic distortion. The proposed methods eliminate this distortion through the novel application of instantaneous symmetrical components. The superior performance and feasibility are verified by experimental and simulation case studies.
	Series compensator for voltage dips: control strategy   By R. Tounsi; P. Michalak; H. Pouliquen; H. Foch	[View]   [Download]
Abstract: Power electronics bring about major improvements to distribution networks. This paper discusses a simulation study on a series compensator capable of smoothing out voltage dips for a low voltage network.
	CONTROL LAWS FOR MV ACTIVE FILTERS   By P. Michalak; H. Pouliquen	[View]   [Download]
Abstract: This paper describes control of an active filter for MV networks using the H2 method and traditional proportional integral control. The results of active filter and control simulations enable comparison of the performance levels of the two control types.
