一种电子管高频功率源定功率灯丝电源改造

摘要

This article introduced the filament power supply technical principle and improvement process of a high fre-quency power source.This technology can reduce the tube start the preheating flow shocks,and prolong the life of the tubes.Transformation result saved the funding of maintenance and electricity,got higher economic benefit.%文章介绍了一种高频功率源的灯丝电源改造的技术原理及改进过程。该技术可以减少电子管启动预热阶段的过流冲击，延长电子管的使用寿命。改造结果节约了维护经费和电费，获得了较高的经济效益。
