ABSTRACT:
A microturbine power generating system includes a battery source for providing startup power. Dc power provided by the battery source is converted to three-phase ac power, and the three-phase ac power is supplied to stator windings of an electrical generator of the system. The three-phase ac power causes the electrical generator to operate as a starter motor. An up chopper may be used to reduce the required voltage of the battery source. A down chopper may be used to charge the battery source during normal operation of the microturbine power generating system. The down chopper can allow the battery source to supply backup power in the event the electrical generator experiences a failure.
