Malosignalni model pretvornika z resonančnim povezovalnim krogomKovačič, Robert ; Milanovič, MiroThe high frequency resonant link converter has been discussed in this paper. The energy has been provided to the resonant tank circuit through the series resonant process. Because of that, the soft ... switch converter operation has been reached. The EMI influences is lower than in the hard switch converter, because the current and voltages have sinusoidal wave-shape and because of soft switching operation. For control purposes the method based on measurement data has been investigated. The MATLAB tool-books ELIS for identification of the small signal model of the ac resonant link converter has been used. For accurate identification of resonant link voltage parameters (i.e. magnitude and phase of the voltage envelope) the Levenberg-Marguardt method was used. The experimental results have shown that this prucedure is capable of providing a good solution of the frequency response fur the investigated system.Source: Zbornik enajste mednarodne Elektrotehniške in računalniške konference ERK 2002, 23.-25. september 2002, Portorož, Slovenija (Zv.
