摘　　要：剖析了双管零矢量与单管零矢量的各自的优劣,针对反向续流问题改进双管零矢量,使新型零矢量可对续流回路截流。为了适应新型单零矢量控制策略,替换原有零矢量,建立了单管零矢量选择表。电机在相同转速、不同负载以及相同负载、不同转速等不同给定条件下进行实验,通过数据分析,发现实验结果高度贴合实验理论。The torque performance of the motor under the zero-voltage vector of two switches was improved based on the existing research. The zero-voltage vector of one switch was established, which could meet the requirements of zero vector in definition and electrical performance and effectively avoided the torque ripple caused by reverse conduction. A new voltage vector selection scheme was established based on zero-voltage vector of one switch. The experimental results of two kinds of zero-voltage vectors under different loads and different speeds were compared to verify the correctness of theoretical analysis.
