可控硅实质上就是一个单方向导电的快速无触点开关。一个性能良好的可控硅每秒钟可以开关2.5万次,速度之快,是一般有触点开关所不能比拟的。我们应用可控硅这个快速开关的性能就可以达到直流电机脉冲凋速的目的。
Thyristor is essentially a unidirectional conductive fast contactless switch. A good performance SCR can switch 25,000 times per second, the speed is fast, the general can not match the contact switch. We use the SCR performance of this fast switch can achieve the purpose of the DC motor pulse rate.
