某雷达发射机行波管灯丝供电设计

摘要

提出采用蓄电池提前给发射机行波管灯丝供电设计，实现蓄电池与电源模块间不间断自动切换供电功能，并给出电路设计原理图的功能描述及软件实现。本系统已经在某型雷达系统应用，功能得到验证，性能优良。%A design of power supply for TWT filament with battery device in advance is presented to implement uninterruptedly automatically supplying power switch between battery and power supply module. The function description of circuit design principle diagram and achievement of software are presented. This design has been applied in a radar system, and the function is verified and its performance is perfect.
