| 摘 要： | 本文利用磁链轨迹控制方法分析了四开关三相逆变桥与两相电机驱动器的相似性.研究表明:由于三相四开关逆变桥只有两相控制绕组完全独立,其基本电压控制矢量组相互垂直,分别控制两组矢量可产生相互垂直的磁场,因此相似于具有垂直磁场控制的两相电机驱动器.利用这一相似性可以简化感应电动机低成本变频调速器的闭环控制.

| Abstract: | Comparability of the three-phase four-switch inverter with two-phase induction motor driver is discussed in the paper by the method of magnetic-flux controlling.It's indicated that there are only two phases independent in the three-phase four-switch inverter.The two basic voltage vector groups of the inverter are vertical each other.With these vectors,the two vertical magnetic fields like two-phase induction motor can be produced.The comparability discussed can be used to simplify closed loop control of low cost converter. |
