Accurate model parameters are important for power electronic circuit design. This paper uses the parameters identification method based on simulation and experiments in which the device interior model parameters are extracted through its exterior characteristics. The method is implemented by optimization. Parameters are identified by minimizing the error between simulated and measured transient characteristics.
