在这项研究中，我们提出了一个改进的综合模型的功率二极管。该模型是基于双极扩散方程（ADE）的数值解的修改有限差分法，使用MATLAB。ADE针对所有进样水平求解，而不是像通常那样仅针对高水平进样求解。考虑了电导率调制、发射极复合、载流子-载流子散射和寿命控制等局部物理效应。温度和自热效应也包括在模型中。该模型已被验证对Silvaco混合模式模拟显示非常好的协议，少得多的模拟时间为我们的模型。为了自包含，我们还提出了一个模型参数提取方法的功率二极管给定其实验瞬态波形。
In this study, we present an improved comprehensive model of power diodes. This model is based on the numerical solution of the ambipolar diffusion equation (ADE) by a modified finite difference method using MATLAB. The ADE is solved for all levels of injection instead of high-level injection only as usually done. Local physical effects such as conductivity modulation, emitter recombination, carrier–carrier scattering and lifetime control are taken into consideration. Temperature and self-heating effects are also included in the model. The proposed model has been validated against Silvaco mixed-mode simulations showing very good agreement with much less simulation times for our model. To be self contained, we also present a model parameter extraction methodology for power diodes given their experimental transient waveforms.
