Abstract
A system includes an engine configured to drive a generator to produce a first power output, and a first inverter communicatively coupled to the generator. The first inverter is configured to convert the first power output into a second power output. The system includes a second inverter communicatively coupled to the generator. The second inverter is configured to convert the first power output into a third power output. The third power output includes a welding power output.
Claims20
A system, comprising:
- an engine configured to drive a generator to produce a first power output, wherein the engine comprises a power rating of approximately 10 horsepower (hp) or less;
- a direct current (DC) bus comprising a rectifier, wherein the DC bus is configured to provide DC power from the first power output;
- an inverter electrically coupled between the DC bus and an auxiliary output circuit, wherein the inverter is configured to convert the first power output into a second power output, wherein the second power output comprises an auxiliary power output;
- and
- a first converter electrically coupled between the DC bus and a welding output circuit, wherein the first converter is configured to convert the first power output into a third power output, wherein the third power output comprises a welding power output.
