| Abstract: | In the abide it is emphasiged to analyze the phenomena of voltage peak and current impact of the GTR ugh as the POwer switcher in the resistance welding inverter controlled by a micro-processor,and its responding proteCting measures, POwer magnetic- divefgrncy liciting, and power voltage surge protecting. The protecting method which combines hardware and software together has the advantages of convenient use, fast response and stability. |
