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 output circuit or the stator winding of the alternator.
A control circuit during a start-up mode switches the inverter circuit to the stator
winding of the alternator and during a power out mode switches the inverter circuit
to the output circuit. During start-up the frequency and voltage of the electrical
power to the inverter is controlled as a function of the time and/or rotation speed.
