微机控制机器人逆变弧焊电源的研究

A Study on Microcomputer Control for Robot Arc Welding Inverter Power Source

根据机器人焊接电源的要求 ,研究了一种由高速单片机 80C3 2 0为控制器的IGBT逆变式弧焊电源。具体分析了其组成结构、主电路和控制电路的工作原理及实现。介绍了电源外特性的获得原理及与机器人通讯过程。实验结果表明 ,该系统可获得多外特性和好的动特性 。

At the special request of robot, this paper study a IGBT inverter arc welding power source which is controlled by high speed single-chip microcomputer 80C320. The principle of the main circuit and its control circuit, and whole system structure are analyzed. The output characteristic of power source and its communication to the robot are also introduced in this paper. The test results show that the system has many output characteristics and excellent dynamic characteristics, adaptable to more robot welding methods.
