초록

The present invention relates to variable speed constant frequency (VSCF) devices and methods for maximizing engine generator efficiency. In one embodiment, a VSCF device may include at least two paths for conducting power to the load. One path, a line inductor path, may advantageously incur minimal power loss when the engine generator is supplying rated power to a load. A second path, a VSCF path, may be used to ensure that the frequency of the power is maintained at a substantially constant frequency under various load conditions. Another embodiment of...

청구항

1. A variable speed constant frequency device that provides at least two paths for power to travel from an engine generator to a load, the device comprising:a standard line path coupled between said engine generator and said load; a variable speed constant frequency (VSCF) line path coupled between said engine generator and said load; and a control circuit coupled to said standard line path and said VSCF line path and that automatically selects the path through which power is routed to said load. 2. The device defined in claim 1, wherein said standard li...
