  • Patent number: 12103118
    Abstract: A dual-pulse MIG welding power source based on SiC power devices may include a main circuit and a digital control circuit. The main circuit may include a power frequency rectifier filter module, a first SiC high frequency inverter module, a first high frequency transformer, and a first SiC fast full-wave rectifier filter module connected sequentially. The power frequency rectifier filter module may be connected to a three-phase AC power supply, and the first SiC fast full-wave rectifier filter module may be connected to a load. The digital control circuit may include a digital human-machine interaction module, a core control module, a SiC high-frequency drive module, a load voltage and current detection feedback module, and a wire feeding control module. The digital human-machine interaction module may be connected to the core control module.
