Development of a Portable AC/DC Welding Power Supply Module

Abstract

This report deals with lightweight power conversion for application and portability in the welding industry. It is a final report on a research contract and it includes all the circuits investigated and their potentials. The report also includes a detail description of the final lightweight circuit used. The supply has a maximum output of 250 amps at 30 volts and either voltage or current could be regulated by a feedback control system. Ninety percent variability is possible with 85 percent efficiency at full load. The unit weighs 98 pounds and is convection cooled only. Input power is 440 VAC 60 HZ 30.
