电压型逆变器不同导电型电压矢量控制研究

A Research for Different Switching-Mode of AC Motor's Voltage Vector Control

本文概述三相感应电动机电压矢量控制原理。分析了电压型逆变器不同导电型电压矢量的分布,并从广义角度推导了不同导电型电压矢量控制的定量关系,讨论了负载及功率因数对不同导电型矢量控制的影响。

In this paper, we have made a detailed discussion about voltage vector's space distribution of voltage inverter with different switching-mode such as 180°,120°,150°,and have formalated voltage vetor control of arbitrary switching-mode. Also, we have discussed the effect of Ioal and power factor on different switching-mode of voltage vector.
