ENGINE DRIVE WELDER AND METHODS AND SYSTEMS OF CONTROLLING THE SAME

摘要

Embodiments of the present invention are engine drive welding and/or cutting systems which optimize the utilization of engine drive systems, including hybrid engine drive systems. Embodiments include modular systems which allow for the remote utilization of a battery powered module which can be separated from an engine drive generator power supply. Other embodiments include engine drive power supplies that can communicate with a load coupled to the power supply, such as welders, cutters and wire feeders to determine an optimum operational level. Further embodiments include engine drive power supplies that can be coupled together to optimize fuel and system usage.

主权项

1. A welding or cutting system, comprising:
a power generation system, comprising:
an internal combustion engine coupled to a generator for generating a power signal;a power conversion circuit which receives said power signal and generates a synchronous output signal;an outlet circuit having at least one outlet which is coupled to said power conversion circuit and receives said synchronous output signal;a first controller which controls an operation of at least said internal combustion engine; anda first communication module which is coupled to said controller; and a welding or cutting power supply coupled to said at least one outlet to receive said synchronous output signal and utilize said synchronous output signal to generate a welding or cutting output signal; comprising:
a second controller to control an operation of said welding or cutting power supply; anda second communication module coupled to said second controller which is in communication with said first communication module; wherein said second controller determines an anticipated power demand for a given welding or cutting operation and generates and sends an anticipated power demand signal to said first communication module; and wherein said first controller uses said anticipated power demand signal to control an RPM speed of said internal combustion engine to adjust a power level of said synchronous output signal.
