Dynamic electrical-magnetic-thermal simulation of magnetic components

This paper describes how the modeling and simulation of electromagnetic devices can be extended to include dynamic thermal effects. The power generated by hysteresis inside ferrite cores is connected to a thermal model of the core material. The thermal conduction of the core material is modeled as is the convection of thermal energy from the core to the surrounding environment. The effective temperature change inside the core is used to modify the parameters of the core material model to accurately reflect the dynamic performance of the device at all temperatures. The electrical circuit, magnetic material and thermal networks are all modeled concurrently in the time domain to allow dynamic interactions across all three domains.
