Abstract

An indirect procedure to couple transient finite-element simulation with circuit simulation is proposed. The procedure is based on extracting lumped parameters from the field simulation and Norton equivalents from the circuit simulation. This approach provides more stability and accuracy because both winding currents and terminal voltages across coupling branches are free to change. It is also more flexible since the finite-element equations and the circuit equations are solved separately and allows complicated system level simulation
