| Abstract: | A control system based on monolithic computer 80C196KC is designed for IGBT welding inverter with submerged arc.The software,hardware,and control principle of the system are introduced.In the power source,a PWM technology is adopted,the PI algorithm with current feedback is used to adjust the volt-ampere output characteristic of the power source.The MOSFET switch power source is applied to the regulating system of wire feeding and tractor traveling.The PI algorithm with voltage feedback is used to adjust wire-feed speed which is controlled with closed-loop.The developed welder has many advantages such as parameter presetting,digital display,and automatic arc starting and stopping functions.The experimental results show that the welder has stable and reliable performance and meets the design requirements. |
