| Abstract: | The designing scheme of main circuit and controlling system for the multi-function IGBT inverter power source with single-chip microcomputer control is researched in this paper.The double inverter technology is used in main circuit,the prior inverter circuit is half-bridge type,and rear inverter circuit is full-bridge.The80C552single-chip microcomputer made in PHLIPS company as core of controlling system is used,so the control circuit is simplified and beneficial to install and adjust.By testing and experiments of a series of waves of power converter,it show s that designs of the hard circuit are rational,procedure running is accurate,parameter regulation is agile,and the reliability is enhanced.The several functions of power source such as DC metal arc welding,DC TIG arc welding,DC pulse arc welding,AC square-wave arc welding and variable polarity AC square-wave TIG arc welding process are realized. |
