Electromagnetic Field Analysis Coupled Model of Fluid–Structure–Thermal Simulation of Power Converter for Switched Reluctance Machine

This paper presents an electromagnetic field analysis coupled model of fluid-structure-thermal simulation of the power converter for the switched reluctance motor drive. The mathematical description is made up of mass conservation equations, momentum conservation equations, and energy conservation equations. The accuracy of the model is verified by comparing experimental data with simulation results derived from the finite-element method. Furthermore, the sensitivity of the distance between the radiator and the fan, the height of the enclosure, and the air velocity of the fan are studied with the proposed model.
