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.
