摘　　要：九开关变换器采用SPWM算法驱动六相电机时,电压利用率低和电流谐波含量较高。针对上述问题,研究了九开关变换器驱动六相永磁同步电机的SVPWM算法。首先介绍了九开关变换器的结构和工作原理,然后阐述了SVPWM算法的具体内容,包括基本电压矢量选择、扇区判断、基本电压矢量作用时间计算、不对称六相时间计算,最后在Matlab/Simulink中进行了仿真实验,验证了所提出算法的可行性。When the nine switch converter uses the SPWM algorithm to drive the six phase motor,it has the disadvantage of low voltage utilization and high current harmonic content. For the above questions,it studied the SVPWM algorithm of the nine-switch converter to drive six-phase permanent magnet synchronous motor.The paper first introduced the structure and working principle of nine-switch converter,and the expounded the specific content of SVPWM algorithm,including basic voltage vector selection,sector,fundamental voltage effect time calculation,asymmetric six phase time calculation. Finally,the simulation experiment was carried out in Matlab/Simulink to verify the feasibility of the proposed algorithm.
