摘要
准确的器件模型参数对电力电子电路设计甚为重要.该文采用实测和仿真相结合的方法,通过器件的外特性辨识其内部物理模型参数.这一方法的实现依赖于最优化算法的运用,通过最优化算法的逐次迭代促使仿真波形向实测波形逼近,从而实现器件模型参数的辨识.
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.
