摘　　要：以带平衡电抗器的双反星形主回路的ZX-5型弧焊电源为对象,对电源静态外特性的形成与控制进行了分析.着重就空载电压的保证与自然下降段电压的提高、陡降段的控制、外拖段的形成等方面提出了新的控制方式,并介绍了相关控制电路的原理.The forming and controlling processes of static output characteristics of ZX-5 arc welding power source are analyzed on the basis of theoretical approach and pratical experiment, the power source consists of a main circuit of double reversal Y-connections along with abalance ind uctor. A new controlling method is put forward to keep the open circuit voltage,enhance the natural decreasing section,control the dropping part and form the dragging section etc. and the principle of related circuets are introduced as well.
