| Abstract: | The researched and developed inversion type arc-welding power source adopt the half bridge-type inversion main circuit that is formed by IGBT, in order to realize inversion step-down and output voltage adjustment. Control circuit is taking pulse wide modulation circuit as core. By comparison of given signal and feedback signal of overvoltage, get the width-adjustable pulse signal for regulating output of welding power source so as to realize the colsed-loop control to arc-welding inverter. |
