串联型稳压电源是电视发射机及一切无线电设备的“油料及粮食”,离开了稳压电源,一切无线电设备都成了一堆无用的废物。本文从电视、微波及无线电设备维修实践出发,对串联型一般电源进行了理论分析,给无线电维修提供了一定的参考和借鉴。串联型稳压电源基本原理就是外界电压发生瞬时变化而引起输出电压变化,则自动调正稳压电源的瞬时高低,就能维持输出电压不变。熟练的分析一切串联型稳压电源基本原理及故障,对无线电维修至关重要。
Tandem power supply is the “fuel and food” of television transmitters and all radio equipment, leaving the regulated power supply, all radio equipment has become a pile of useless waste. Based on the practice of TV, microwave and radio equipment maintenance, this paper analyzes the theory of series-type general power supply and provides some references for radio maintenance. The basic principle of series power supply is the instantaneous changes in the external voltage caused by changes in output voltage, then automatically adjust the instantaneous level of power supply, will be able to maintain the same output voltage. Skilled analysis of all the basic principles of series power supply and failure, the radio maintenance is essential.
