Abstract: A novel high power pulsed metal inert-gas (MIG) welding inverter power supply based on digital signal processor (DSP) was introduced in this paper. In order to meet the requirements of the pulsed waveform modulation of pulsed MIG welding, according to the modulation principle of pulse power supply, a pulse width modulation (PWM) waveform which used in full-bridge inverter was produced based on DSP. The proposed pulsed MIG welding inverter power supply was tested on the external characteristics, the dynamic characteristics and high power output. The results indicated that the novel pulsed MIG welding inverter power supply possessed excellent dynamics and static characteristics and reliably high power output performance, which can meet the requirements of pulsed MIG welding well.
