Hybrid welding-type power source

摘要

The present invention is directed to a welding-type power source that includes a power source housing and an engine arranged in the power source housing to supply electrical power. An energy storage device is included that is in rechargeable association with the internal combustion engine and arranged to provide welding-type power for at least a given period.

主权项

1. A welding power source comprising:
an engine driven generator configured to produce electrical power for a welding operation; an energy storage device coupled to the engine driven generator and charged by the engine driven generator, the energy storage device configured to provide electrical power for the welding operation; and a detection circuit coupled to the engine driven generator and configured to detect whether the engine driven generator is producing sufficient power for maintaining the welding operation; wherein electrical power from the engine driven generator and electrical power from the energy storage device are provided to the operation in parallel and at the same time, and wherein the electrical power from the energy storage device is provided for the welding operation when the electrical power of the engine driven generator is insufficient to provide operational power.
