Power transformers model used for inverters simulations

Abstract

This paper intends to present a model of power transformers used in simulation of power inverters. Electromagnetic induction refers to the phenomenon by witch electric current is generated in a closed circuit by the fluctuation of current in another circuit placed next to it. For modeling of power transformers, we implemented a Matlab software, based on mathematical equations who describe the functionality of power transformers. Also we compare the Matlab results with a Pspice simulations results. Matlab program that we've implemented enables the modification of input parameters of the transformer and the choice of a circuit to be analyzed. Also the Matlab model permits to view the waveforms of circuits in transient or steady state regime.
