초록

The present invention provides systems and methods that allow for individual power sources to be disconnected and reconnected without interrupting the power supply from the other power sources and that allow for these power sources to provide power at substantially the same electrical parameters such as frequency, phase, and voltage.

대표
청구항

The invention claimed is: 1. A method for supplying power to a load using multiple power sources, comprising: providing power comprising a first value of a parameter from a first power source to the load; monitoring the first value; providing power comprising a second value of the parameter from a second power source to the load, wherein the second value comprises substantially the first value when the first value is within a range of values for the parameter and is within the range when the first value is outside the range; disconnecting the first powe...
