摘　　要：本文针对五相永磁同步电动机,构建了三电平逆变器供电的调速系统。在对五相三电平逆变器的电压空间矢量进行详细分析的基础上,通过合理选择冗余矢量,提出了五相三电平逆变器最小开关损耗SVPWM(MSLSVPWM)控制方法。该控制方法开关损耗最小,并可有效降低开关器件的最大开关电流,并通过仿真实验对该控制算法进行了验证。The paper,focusing on five-phase permanent magnet synchronous electromotor,constructs speed-adjustment system for power supply of three-level inverter.Based on detailed analysis on the voltage space vector of five-phase three-level inverter and by reasonably selecting surplus vector,the author advances control strategy of minimal swtich wastage SVPWM（MSLSVPWM） for five-phase three-level inverter.The control strategy can minimize the wastage of switch and in the meantime can lower max switch current of switch components.The author tests the control arithmetic by simulated experiments.
