一种实用的开关稳压恒流气体激光电源

Pratical constant current switching power supply of gaslaser

本文报道了我们研制成功的一种新型气体激光开关稳压恒流电源。设计制作的特点是：引入２０ｋＨｚ开关电路，丢弃次级高压的工频变压器，选用现行彩电行输出变压器和通用集成模块，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。电路结构更趋小型化、高频化、集成化与通用化。测试与应用结果表明本电源具有优良的性能／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 20 kHz switching circuit and giving up the high voltage line transformer. Especially we use existing TV horizontal output transformer and normal IC to produce continual adjustable lightup voltage and constant working voltage for various HeNe laser. This circuit’s size is very small. The result of testing and application of this circuit proves that is has superior ratio of quality versus price, and easy made.
