Abstract

This paper reviews magnetic circuit models of magnetic structures, developed as analogs of electric resistor networks. It demonstrates magnetic simulation by circuit simulation of a magnetic circuit representing a three-winding magnetic structure, using known winding currents to calculate magnetic fluxes. Simultaneous simulation of both a magnetic circuit representing a magnetic structure and electric circuits connected to the windings eliminates the need to specify winding currents as known independent sources. This technique is here termed "co-simulation" for brevity. The controlled sources and auxiliary circuits necessary to implement co-simulation are arranged with winding turns as factors in controlled sources, to allow easy adaptation for different windings. Co-simulation is illustrated using the same three- winding structure used in the magnetic simulation, with a pulse input to one winding and a resistive load on the other two windings. The results of this co-simulation are compared to an electric circuit simulation in which the magnetic structure is described with three self inductances and three coupling coefficients. Extensions of co-simulation to account for nonlinear magnetic core behavior and core loss are described.
