two speed ac control

基本解释

All the AC speed regulation approaches can be generalized in two basic schemes, the electromagnetic power control and the loss power control.
损耗功率控制增大的是转速降，调速是低效率的。
The serial communication control between PC and one DC speed regulators and two AC inverters is realized by using USS protocol based on the RS485/232 interface.
采用基于RS485/232接口的USS协议实现了工控机与一台直流调速器和两台交流变频器的串行通信控制。
SRD is the second DC converter, AC speed up after the development of a new type of speed control system by the switched reluctance motor and controller of two parts.
开关磁阻电机调速是继直流调速、交流调速后发展起来的一种新型的调速系统，由开关磁阻电机及控制器两部分组成。
