介绍一种晶体管恒流全新触发连续固体激光器氪灯电源。先用一较高电压的辅助电源触发氪灯进入辉光放电 ,然后接通主电源 ,通过控制电路使氪灯自动过渡到弧光放电。为使氪灯正常工作电流恒定 ,光强稳定 ,采用晶体管恒流电路控制氪灯电流 ,从而使整机电路简化 Describes a new transistor constant current continuous trigger krypton lamp solid state power supply. First use a higher voltage auxiliary power to trigger the krypton lamp into the glow discharge, and then connected to the main power supply, krypton lamp automatically transition to the arc discharge through the control circuit. In order to make the normal working current of krypton lamp constant, the light intensity is steady, the transistor constant current circuit is used to control the krypton lamp current so that the whole circuit is simplified
