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 the invention describes a process for determining optimal engine generator speed for a particular load. Because engine speed can be varied using any VSCF device, this process determines a speed that minimizes fuel consumption, emissions, and noise pollution for a given load.
A multiple path system for providing power from a power source to a load, said system comprising:
A method for selecting a path through which power is routed from a power source to a load, said method comprising:
For use in a power supply system having an engine generator that generates power for a load and a variable speed constant frequency (VSCF) device for routing power from said engine generator to said load, comprising:
