Finite element analysis of saturable lossy magnetic components is extended to include the effects of switches, which may be either mechanical or electronic. The switches are modeled using coupled electromagnetic and structural finite elements which are stretched tovay their electrical resistance with time. Good results are shownfor asimpleresistivecircuitwith aswitchedexcitation and forahighlysaturated transformerwithasecondayloadresistor that is switched on and off.
