分析了几种传统的双电机逆变器拓扑。针对存在的问题,提出了一种改进的逆变器拓扑,弥补了传统逆变器拓扑控制复杂且很难独立控制两台电机的问题。在MATLAB/Simulink环境下建立基于该逆变器的永磁同步电机矢量控制的仿真模型。仿真结果表明,所提改进的逆变器拓扑可以实现独立控制且控制简单。

Several traditional dualmotor inverter topologies were analyzed. Aiming at the existing problems, an improved inverter topology was analyzed, which made up the problem. The traditional inverter topology control was complex and it was difficult to control the two motors independently. The simulation model of permanent magnet synchronous motor vector control in MATLAB/Simulink environment was established. The simulation results showed that with the improved inverter topology two motors could be controlled independently and the control was simple.
