摘要
提出了一种基于间接矩阵变换器(IMC)5桥臂逆变器的双电机矢量控制方法,该方法将IMC 5桥臂逆变器的电压矢量脉宽调制(SVPWM)策略与异步电机的矢量控制相结合,实现了2台异步电机的独立控制和较好的动静态性能。相比于传统IMC双电机传动系统,该系统的开关器件数目进一步减少,从而降低了系统成本,提高了系统的效率。另外,该系统也可以作为传统IMC双电机传动系统一个桥臂故障情况下的容错运行模式。仿真结果验证了所提系统的有效性和可行性。
A dual induction motor drive system fed by an indirect matrix converter（IMC） with five-leg inverter was investigated,which combines vector control technology for motors and SVPWM algorithm for IMC with five-leg inverter. The proposed control strategy shows independent control of the two motors in the drive system and high stat- ic/dynamic performance. Compared with conventional dual-output indirect matrix converter, the proposed converter has lower cost and higher efficiency. In addition, the system can also be used as a fault tolerant operation when one bridge of the traditional IMC dual-drive system is broken.Simulation results show the effectiveness and feasibility of the proposed system.
