摘　　要：本文主要介绍新型的开关式场效应管弧焊电源的工作原理。通过采用电流负反馈获得恒流外特性,并提出了一种新颖的低压引弧电路。利用所研制的开关式场效应管弧焊电源进行引弧试验和工艺试验,结果表明,此电源具有良好的引弧性能和工艺性能,是一种发展前景较远大的电子弧焊电源。The paper mainly deals with the basic principles of the switched MOSFET arc welding power source The feedback of current is used to obtain the constant eurrent characteristics. A new low voltage arc-ignition circuit has been put forward. The satisfactory tests of arc-ignition and good properties of welding process may prove this switched MOSFET arc welding power source to be an electronic power source with broad prospects.
