This paper mainly introduces the electrical characteristics of the Robot MOSFET Arc Welding Invertor and its arc welding technological properties. Emphases are laid on the analyses of the current and voltage wavefonns of the main circuit as well as the energy loss of the MOSFETs. The different static characteristic curves and parameters of electrical reactance are also discussed.

研究了机器人场效应管式弧焊逆变器的电气性能和弧焊工艺性能，并着重对其逆变主电路电流、电压波形、管组功耗进行分析研究，以及探讨如何采用不同形状的外特性曲线与合理设计电子电抗器的电参数，从而提高弧焊机器人对不同工件开关、不同弧焊方法的适应性，实现贫飞溅的焊接。
