摘要
晶闸管变流装置通过改变触发控制角α从而改变装置的输出电压ud,而α角与触发器电路的控制电压UK之间有着密切关系。正确分析与探索控制电压UK与输出电压ud的关系,从而为变流装置实现过流保护和闭环自动控制提供了一个平台。
The SCR convertor devices change the output voltage ud of the devices with the change of the triggering angle α.However,there is colose relation between angle α and the controlling voltage UK of the triggering circuit.This paper analyzes and explores the relation between the control voltage UK and the output voltage ud ana provides a platform for the over-current protection and the automatic control of the convertors.
