Abstract: 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.

Abstract: The present invention is directed to an active converter system for a permanent magnetic turbogenerator. A system in accordance with an embodiment of the present invention includes a DC voltage link and a first active converter including a connection for inputting or outputting a three-phase AC voltage to or from, respectively, an AC voltage source, another connection for inputting or outputting a DC voltage from or to said DC voltage link, and at least six selectively switchable first IGBTs, wherein selective switching of the first IGBTs results in a boosted DC voltage. The system further includes a second active converter including a connection for inputting or outputting a three-phase AC voltage to or from, respectively, a permanent magnetic generator, another connection for inputting or outputting a DC voltage to or from said DC voltage link, and at least six selectively switchable second IGBTs, wherein the second active converter is capable of boosting said DC voltage.
