摘　　要：对称六相PMSM双电机串联系统由一台对称六相PMSM串联另一台三相PMSM,在同一台六相电压源逆变器驱动下实现解耦运行。直流母线电压利用率的提高是该串联系统的关键问题之一。本文计算出了对称六相PMSM双电机串联系统逆变器工作在线性调制区的临界条件,分析了零序信号注入提高载波PWM直流母线电压利用率的方法,并通过Mtalab/Simulink仿真对几组工作点进行了验证。The driver system symmetrical six-phase two-motor connected in series consists of one symmetrical six-phase PMSM and the other three-phase PMSM connected in series. The system is supplied by a six-phase voltage source inverter. The increase in the DC-bus utilization is one of the central issues of the series-connected driver system. This paper figures out the limit of the liner modulation region and analyzes the method increasing the DC-bus utilization of carrier-based PWM with the offset injection. Some operating points are verified by using of Matlab /Simulink
