Simulation of power converters has traditionally been carried out using simplified models to shorten simulation time. This will compromise the accuracy of the results. A proposed fast simulation method for simulating converter losses and device temperatures over long mission profiles (load cycles) is described in this paper. It utilises accurate physics-based models for the device losses, and is validated with experimentally obtained results.
