The 3D coupled field-circuit simulation of transients in converters with conducting solid parts

An algorithm for a simultaneous solving of equations of the 3D electromagnetic field and equations of electric circuits of an electromagnetic device with a solid conducting part has been elaborated. The A-T formulation has been applied, In order to solve the 3D problem a special iterative procedure, in which the 3D task has been substituted with an iterative sequence of 2D problems, has been proposed. The dynamic operation of the electromagnetic device is also considered.
