在许多气体激光稳流电源中,采用将稳流控制器与气体激光管串联的被动稳流方式.这种方式与采用将取样电阻和气体激光管串联的主动稳流方式相比,具有电路简单、调整方便、输出电容小、工作可靠等优点.但由于对稳流控制器的耐压要求高,因而限制了它的应用.为了减小稳流控制器上电压的变化,扩展可工作的电网电压范围、提高稳流精度,一个简单而又有效的方法是采用整流型恒压变压器.
In many gas laser steady-state power supply, the steady current controller and the gas laser tube in series with the passive steady flow way.This way and the sampling resistor and the gas laser tube in series active steady flow compared to a simple circuit , Easy to adjust, small output capacitance, reliable work, etc. However, due to the high voltage regulator of the steady flow controller, thus limiting its application.In order to reduce the steady flow controller voltage changes, expanding the work of the power grid Voltage range, improve steady flow accuracy, a simple and effective method is to use rectified constant voltage transformer.
