| 摘 要： | 针对功率MOSFET关断时寄生参数对死区时间的影响问题,基于SIMPLIS仿真软件和MOSFET的特点,建立MOSFET的仿真分析模型,并研究MOSFET寄生参数与电路中米勒平台及关断时间的关系。建立MOSFET的寄生电容分段线性模型,应用Matlab软件实现参数的对比分析,根据内部器件的工作原理确定其转移特性和输出特性,利用图像数据获取MOSFET的等效模型,采用MOSFET搭建LLC谐振变换器电路,通过不同条件下的仿真实验,得到寄生参数的影响规律。一系列的仿真训练能够有效提高学生的仿真实践能力。

| Abstract: | Aiming at the influence of parasitic parameters on the dead time of power MOSFET,based on SIMPLIS simulation software and the characteristics of MOSFET,this paper establishes a simulation analysis model by MOSFET,and studies the relationship between the parasitic parameters of MOSFET and the Miller platform and the turn-off time in the circuit.The piecewise linear model of parasitic capacitance of MOSFET is established.Parameters are compared and analyzed by MATLAB software.Transfer and output characteristics are determined according to the working principle of internal devices.An equivalent model of MOSFET is obtained by image data.The electric circuit of LLC resonant converter is built by MOSFET.The influence rule of parasitic parameters is obtained by simulation experiments under different conditions.A series of simulation training can effectively improve students'simulation practice ability. |
