| Abstract: | The double closed loop and constant output current control system is proposed for single arm and positive exciting inverter. It can realize fast and no surging of the output current control in the whole course of arc resistance varying scope, and the simulation as well as experiment show that the system is both fast response and high accuracy ,not only is it satisfied with CO 2 welding, it also protect IGBT inverter from over current as well. |
