초록

An electrical system for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an AC output circuit or the stator winding of the alternator. A control circuit during a startup mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the AC output circuit. Thus, during the startup mode, the alternator functions as a motor to raise the speed of the turbine to a safe ig...

What is claimed: 1. A method for controlling a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator, the method comprising: a startup process to provide startup electrical power to the turbine/alternator through an inverter section to controllably rotate the permanent magnet alternator to start the turbine/alternator; and a power output process, after the turbine/alternator has reached speeds necessary to sustain operation of the turbine, to reconfigure the inverter section to extract output electrical power for providin...
