Influence of hysteresis on the behaviour of coupled finite element-electric circuit models

Abstract

This paper describes the computation of waveforms of electrical current and voltage in inductances, taking into account the hysteresis phenomenon and electric circuit equations. The non-linear transient magnetic field is computed with the finite element method. The classical nonlinear case is compared to the hysteretic one: it is shown that hysteresis has a crucial importance on the waveform by introducing asymmetry and damping, and by modifying the natural frequency of the oscillations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
