Abstract
A combined field and circuit approach in time domain is presented in this paper for the realistic study of power frequency devices. The field analysis is performed by an explicit, conditionally stable, finite difference scheme that allows the whole procedure to take place in time domain avoiding large, sparse matrix inversions, a significant shortcoming of implicit methods. The circuit equations are also considered in time and are easily coupled to the field analysis technique via branch currents and conductor voltage drops. The preliminary results by corresponding 2-D problems reveal the algorithm’s ability to accurately model transient phenomena.
