Publication number: 20180117698Abstract: Hybrid welding modules are disclosed. An example hybrid welding module includes a welding input switch, an energy storage input switch, an energy storage output switching circuit, and a control circuit. The welding input switch receives welding-type input power and selectively outputs the welding-type input power to a weld circuit as first welding-type output power. The energy storage input switch receives the welding-type input power and selectively conducts the welding-type input power to an energy storage device. The energy storage output switching circuit converts energy output by the energy storage device to second welding-type power and outputs the second welding-type power to the weld circuit.Type: ApplicationFiled: October 31, 2016Publication date: May 3, 2018Inventor: Quinn William Schartner
