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.

Robust power distribution systems and methods

A system and method for controlling a microturbine generator system comprising: providing a computer control unit; providing a utility power grid sensor input line to the computer control unit; and providing a utility power grid disconnect command output line from the computer control unit; and causing, via the computer control unit, automatic transitions of the microturbine generator system between at least four states, the at least four states comprising a generator standby backup mode, a generator standalone mode, a transfer to standby backup mode, and a generator startup battery charging mode.

Automatic mode transitions for microturbine generating systems

A microturbine power generating system and associated method for managing a battery source associated with a microturbine power generating system is disclosed. The system and methods enable charging the battery source from the utility grid when the turbine is not running and providing load support when the microturbine engine is unable to support a transient load.

Systems and methods for managing a battery source associated with a microturbine power generating system

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.
