Accurate thermal models are very important to precisely calculate the losses in power devices. Typically, 1D thermal models are used for this purpose as they can be easily integrated in power electronics simulation tools such as Simba... and can solve very quickly.
However, they often lack in accuracy, which normally leads to large temperature margins in the selection of the power devices, and therefore overengineered and more expensive converters. The proposed method runs a co-simulation between Simba and scStream, a thermo-fluid software of the Hexagon portfolio, where a high-fidelity thermal model is implemented.
An automotive on-board-charger, developed by the Hexagon Applied Solution group, is used as a case study.
