Three phase converter circuit using thyristor switch

hppc实验的数据分析，重要参数的提取，本代码适用于二阶等效电路，可以计算其中的串联电阻，并联的RC电路中的参数的值是多少，另外可以提取相应的每一个步骤所对应的开路电压，电流，以及对应的实验的时间。(hppc experimental data analysis, extraction of important parameters, the code for the second equivalent circuit can be calculated as one of the series resistance of the parallel RC circuit of the value parameter, the other can extract the corresponding corresponding to each step The open circuit voltage, current, and time of the corresponding experiments.)

通过左片的同名点在右片进行相关系数匹配，最后得到相关系数匹配结果。(Piece by the same name in the left and right point correlation coefficient matching pieces, and finally get the correlation coefficient matching results.)

一个简单的发动机模型，大家可以互相学习，这个模型是别人做建立的(A simple engine simulink model )
