摘要
An inverter type power source system for robot arc welding is considered. The power source includes several isolated gate bipolar transistor (IGBT) inverter power units. The output current of every individual power unit is regulated by an identical single chip microcomputer to enable the whole power source system to work over a wide range of continuous output current with good dynamic properties. This inverter type power source satisfies robotic welding requirements.
