一种新型开关稳压恒流气体激光电源

A new constant current switching power supply of gaslaser

报道了已研制成功的一种新型的开关稳压恒流气体激光电源。制作特点是：引入２０ｋＨｚ开关电路和晶闸管，丢弃笨重的工频变压器，选用现行彩电行输出变压器和通用集成电路，用以产生连续可调的起辉电压和恒流工作电压，供不同管型ＨｅＮｅ激光器选用，具有优良的性能／价格比，且易于自行制作。

This artical describes a new constant voltage and constant current gaslaser switching power supply.The feature are using 20kHz switching circuit and thyristor circuit and giving up the heavy line transformer.Especially we use existing TV horizontal output transformer and normal IC to produce continuous adjustable lightup voltage and constant working voltage for various HeNe laser.It has superior ratio of quality versus price and easy made.
