Beschreibung
Zusammenfassung:	A gas turbine of an aircraft includes start-up system configured to drive a shaft of the gas turbine in rotation. The start-up system includes a control system and a brushless asynchronous electric machine and is supplied with a DC voltage. A method for starting the gas turbine includes the steps of converting the DC voltage into a three-phase voltage control system based on a first value representative of a rotational speed of a rotor of the electric machine and on a second value representative of a ratio of a determined target torque of the electric machine, suitable for driving the rotation of a shaft of the gas turbine at a determined speed, to the maximum theoretical torque that the electric machine is able to produce at the determined rotational speed of the rotor.
