Abstract :
Digital simulation of audio transformers is discussed in this paper. A simplified model of the audio transformer is designed. The model is described using nonlinear differential equations. The transformer core is modeled by Jiles-Atherton and Frohlich models. The whole system is approximated in order to reduce computational complexity. Finally, the proposed algorithm is tested in real-time and the computational complexity is determined.
