摘　　要：阴控高功率速调管阴极工作在高压脉冲状态,灯丝电源悬浮在随阴极脉冲变化的电位上,开关稳压电源直接工作在阴极电位,极易受高压脉冲干扰无法工作。介绍了一种AC 220V输入低压端控制的恒流灯丝电源,具有抗干扰强、稳定度和可靠性高等特点。The cathode of high power cathode-controlled klystron always operates in the state of high-voltage pulse.The floating potential of filament power supply changes with the pulse voltage of cathode.When the switching regulated power supply directly operates at the cathode potential,it is easy to be interfered by high-voltage pulse and unable to work.This paper introduces a constant current filament power controlled by AC 220 V input low-voltage,which has the characteristics such as better anti-interference ability,stability and reliability.
