summary

This report is a part of continuing project. The aim of this project is to create a semi-automated method for estimating of the transformer parameters. In this project we use self-resonant frequency to get the best frequency. In addition, we use 1-port device and 2-port device. In order to test some of our calculations, we will disassemble some transformers. We can obtain absolute measurements of the numbers of turns, and core-dimensions. Obviously, we will combine a variety of measurements, with some mathematical methods, to estimate the parameters of transformers. One important method is, Least Square Spectral Analysis (LSSA). If the transformer is operating in a non-linear mode, under conditions of high current, for example the resulting distortion will produce higher-order components in the Fourier series, which can be estimated using a modification of the LSSA method. Previous work has shown that Transmission-Parameters lead to a simple formulation of our problem.
