Patent abstract
A method and apparatus for providing welding-type power includes receiving an input that may be either a single or a three phase input voltage. Three power modules, each having a single phase boost power circuit, and an output circuit process the input power. A weld output circuit receives and combines the outputs of the three power modules. An input power distribution module connects the three power modules such that each receives a unique single phase power signal. A controller controls the three power modules and the input power distribution module.
