Title: GENERATOR FOR ARC WELDING MACHINES
Abstract:
A generator for arc welding machines provided with an input rectifier stage (101) which has a unit power factor and comprises an inductor (107), on the main side, two diodes (109, 110) and two electronic switches (111, 112), one for each diode, which are driven by a driver which renders the absorption of the input rectifier stage practically sinusoidal.
