| 摘 要： | 针对异步电动机在三电平逆变器供电下，其恒转矩区域运行时的特点，提出一种直接转矩复式控制技术．根据不同的运行速度，选用不同的电压空间矢量进行线性组合，控制电机的定子磁链和电磁转矩．通过仿真研究，该方法既能优化功率器件的开关频率，同时又有效抑制了三电平逆变器中点电压的偏离，提高了传动系统的整体性能．

| Abstract: | The paper presents a direct torque's compound control technique,which means to select different voltage vector varying from speed,working on constant torque area when the induction motor is fed by three-level inverter.Simulation results of the method for a three-level inverter feeding induction motor are presented.The simulation results confirm that the control method is very effective in optimizing the frequency of switching devices,balancing the neural point voltage of three-level inverter,and improving drive system performance. |
