This paper presents a method to combine CFD simulation with electrical simulation packages. This approach leads to highly accurate electro-thermal system modeling for DC-DC converters. Based on an initial power loss of main components and a thermal model of the converter, a user friendly CFD thermal simulation is used to obtain an initial point for case steady-state temperatures. These set of temperatures are then fed into temperature-dependent electrical models and simulations. The procedure can be repeated while error levels remain within an acceptable range. This approach can lead to a relatively accurate electro-thermal model at steady state
