Article Preview

The main and control circuit of co2 welding power, which is mode of full-bridge and IGBT inverter, is designed based on DSP (Digital Signal Processor). The designing include sub-modules based on DSP such as the sampling signal circuit, the control circuit for external characteristics, the PWM (Pulse-Width -Modulation) control circuit of welding inverter, the IGBT drive circuit and etc. This designing can strengthen the reliability of feedback regulation property on co2 inverter welding power can enhance the stability of the parameters from the power system. The experimental result shows that the inverter welding power has good feedback regulation and stability properties during the co2 welding process.
