Abstract

The most efficient technique for solving field-circuit coupled problems is to use an equivalent circuit for the electromagnetic device. This paper describes a general technique for determining reduced-order circuits starting from the field equations discretized with the Finite Integration Technique (FIT). Special boundary conditions ensure the good formulation of the coupled problem. Pade Via Lanczos (PVL) techniques are used for reducing the state-space form of the system. The proposed approach eliminates the need to actually solve the field problem in order to extract the parameters of the equivalent circuit
