实现三电平逆变，达到直流电变化为有两头波动的交流波形，此电路稍微修改一下时间，就可以转化为整流电路(To achieve three level inverter, to achieve direct current changes for the two sides of the AC wave fluctuations, this circuit slightly modified time, you can translate into rectification circuit)

修改版的带牵入转矩倍数的异步起动永磁同步电机电机计算程序(A modified version of an asynchronous starting PMSM motor with multiple torque multiplier)

对200hz信号的采样，可稍作修改作为信号采集基本模块。(The sampling of 200Hz signal can be modified as a basic module of signal acquisition.)
