矩形波交流弧焊电源的研究

Study on Alternating Arc Welding Power with Rectangle Wave

利用ＩＣ一ＳＣＲ控制将正弦波交流直接转换成矩形波交流，研制了一种工频矩形波交流弧焊电源，并设计了垂直陡降加外延的电源外特性。

alternating sine wave changes directly into alternating rectangle wave byuse of IC- SCR control and an alternating arc welding power with rectangle wave is devel-oped.its outside characteristic of vertical-drop and extension are also designed.
