Implementation and Comparison of Power Diode Models for System Simulation

This paper presents the development and implementation of power diode models in MATLAB/Simulink. The dynamic charge model, lumped charge model and the Fourier-series-based model are validated against the 2D device simulator Silvaco ATLAS. The accuracy, speed and simplicity of the models are also compared. The implementation of the dynamic charge and lumped charge models enable the straightforward realization of models for other power devices in MATLAB/Simulink. This promises to be useful for the simulation and optimisation of complex systems, while accommodating key aspects of device behaviour
