Abstract

Diode rectifier has been widely used as he preregulator of inverter arc welding machine(IAW). As it is linked to power utility a disorder of other instruments can be burst out. The adoption of voltage source PWM converters can be considered and which must catch the compromise of between performance and cost. So in this paper voltage source PWM converters which have single (i.e. PWM converter) control switch respectively are analyzed and evaluated through digital simulation and experiment. In addition the improved input characteristics of IAW are shown and compare to those of conventional one.
