Model of emi filter for asymmetrical measurement setup in standard method
Jiří Zachar, Zdeněk Kejík, Jiří Dřínovský · International Conference Mixed Design of Integrated Circuits and Systems · 2011
In Introduction are introduced main problems of measurement of EMI filter. Reduced equivalent circuitries for EMI filter are shown. Two optimization routines, Quasi-Newton method and Levenberg Marquardt, were introduced for nonlinear least-squares problems. The spurious elements of filter in asymmetrical measurement setup are searched by Quasi-Newton method. Both own and spurious parameters was searched by Levenberg Marquardt method. Results of both approaches are shown.
