摘　　要：首先确定电压矢量所在的区域,然后通过伏秒平衡原理推导出基本矢量的作用时间,根据三电平逆变器输出性能要求优化了空间电压矢量的作用顺序。MATLAB/SIMULINK仿真实验表明,该控制算法可以减小控制算法的复杂性,提高逆变器的输出性能。First the section of the reference voltage vector is determined and then the working time of the vector is deduced with volt-second balance principle. To meet the needs of the output indexes of the three level inverter, the sequence of space voltage vector is optimized. MATLAB/SIMULINK based simulation show that the algorithm can reduce calculation complexity and improve the performanceof the inverter.
