Abstract:
1. A method of controlling a turbine/alternator comprising a gas driven turbine and permanent magnet alternator on a common shaft comprising: providing electric power to said turbine/alternator through an inverter circuit that outputs electrical power to said turbine/alternator at frequencies and voltages required to start said turbine/alternator to achieve self-sustained operation of said turbine/alternator; reconfiguring said inverter circuit by switches internal to the inverter circuit to output electric power from said turbine/alternator at desired frequencies unrelated to turbine/alternator rotation speed when self-sustained operation of said turbine/alternator is achieved; and monitoring turbine operation parameters prior to self-sustained operation to activate the reconfiguring step and to monitor and control turbine operation before and after the reconfiguring step.
