摘　　要：构建TSC主电路结构电路模型,应用拉氏变换对其电路模型进行分析,得出TSC投切无过渡过程所应满足的条件;利用MATLAB的simulink模块搭建仿真模型,得到了不同投切时刻电容器组的电压和电流波形,同时对不同拓朴结构TSC的投切过程进行了对比;最后对实际的TSC过零投切过程得出了合理的结论。The paper construct the circuit model of TSC, using Laplace transform to analyze the model, then obtained the condition which non-transition process of TSC switching;this paper construct the simulink model of TSC and debug it. Record the current and voltage waveform of the switching process and contrast different construction of TSC. In the end of this paper, make a true conclusion of process which voltage-zero switching capacitor in reality.
