Finite element analysis of induced currents in axisymmetric multi-conductors connected in parallel to voltage sources

A method for analyzing induced currents, including both eddy currents and circulating currents, in axisymmetric multiconductors connected in parallel to voltage sources has been developed using the finite-elements method. The method has the advantage that the nonlinear analysis of induced currents in conductors connected to voltage sources with distorted waveforms (for example, an inverted-fed transformer) is possible. Because the method can take into account the voltage sources, the external impedances, and the nonlinearity of the core it becomes possible to analyze flux and current distributions under actual operating conditions and to design windings which produce the minimum power loss. The effectiveness of the method is illustrated by applying it to a transformer model
