电力变流设备中的激光光源控制

The Power Convertor Equipment With Laser￣light Sources Control

论述了在电力变流技术中，应用红外波段激光光源控制高压大功率光控晶闸管（ＬＴＴ）换流阀的一些技术与理论问题．给出了激光光源的选取原则．论述了光耦合问题。

This paper discussed and analised the questions about applying infrared rays Laser-light source to control the high voltage and high power lightttriggerde thyristors LTT in convertor technique. Selection rules of the laser--light source, photo-coupling, the model of photoelectronic converting about LTT converting valve and calculated method about photo curent. are given.
