薄板氩弧钎焊专用电源研究

Study on the TIG Soldering Power Source

氩弧钎焊的电弧电流小、稳定性和指向性差，对电源提出了特殊要求，文中讨论氩弧钎焊专用电源的设计问题，分析了异步通断式逆变器、中频脉冲和高频回避电路在此类电源中的作用．

The arc of TIG soldering has small current,less stability and less oriented.This raises special requirement to the power source.In the present paper the design of TIG soldering power source is discussed.The analysis to the application of phase shift inverter,the mid frequency pulse and the HF avoiding technology is also presented.
