Patent ID: 8847560

Claim:
A power supply circuit for supplying electrical energy in an aircraft, the circuit comprising: a power supply generator configured to be driven in rotation by an engine of the aircraft to power electrical equipment of the aircraft engine, the power supply generator comprising an asynchronous machine connected to an excitation device; the asynchronous machine including a rotor configured to be driven in rotation by the engine and a stator connected to the electrical equipment; and the excitation device is configured to cause a reactive current of flow in the stator; wherein the excitation device includes one or more capacitors; and the asynchronous machine presents magnetization inductance Lm expressed by relationship: L m = L 0 ⁢ I μ ⁢ ⁢ 2 α I μ ⁢ ⁢ 2 α + I m α in which L 0 is magnetization induction at zero current, I μ2 is magnetization current that decreases the magnetization inductance L m by a factor of 2, I m is magnetization current, and α is a coefficient that depends on characteristics of the asynchronous machine, wherein α is less than 2.5.
