An electrical power supply device for an aircraft on the ground, the device including two electricity generators driven by an auxiliary power unit, wherein the first generator is connected by a selective connection/disconnection mechanism to an aircraft network and to an electrical taxiing network,
An electrical power supply device for an aircraft on the ground, the device including two electricity generators driven by an auxiliary power unit, wherein the first generator is connected by a selective connection/disconnection mechanism to an aircraft network and to an electrical taxiing network, and is configured to deliver either a first AC voltage to the aircraft network when it is connected to that network, or an AC voltage or a power to the taxiing network when it is connected to that network, and wherein the second generator is connected by the connection/disconnection mechanism to the aircraft network to deliver the first AC voltage to that network solely when the first generator is powering the taxiing network.

1. An electrical power supply device of an aircraft disposed on a ground, the device comprising: first and second electricity generators driven by an auxiliary power unit,the first electric generator powers an electrical taxiing network including electric motors for driving wheels of the aircraft,the second electricity generator powers an aircraft electricity network,wherein the first electricity generator is connected by selective connection and disconnection means to the aircraft electricity network and the electrical taxiing network,wherein the first electricity generator delivers a first AC voltage to the aircraft electricity network when connected to the aircraft electricity network, and delivers one of a higher AC voltage and an electrical power to the electrical taxiing network when the first electricity generator is connected to the electrical taxiing network, andwherein the second electricity generator is connected by the connection and disconnection means to the aircraft electric network to deliver the first AC voltage to the aircraft electricity network only when the first electric generator is powering the electrical taxiing network, and is disconnected by the connection and disconnection means to the aircraft electricity network when the first electricity generator is powering the aircraft electricity network. 2. A device according to claim 1, wherein one of the generators is a starter/generator configured to start the auxiliary power unit. 3. A device according to claim 2, further comprising an electronic power unit connected to the starter/generator for controlling the starting of the auxiliary power unit. 4. A device according to claim 1, wherein the first generator is a three-stage synchronous generator with wound rotor excitation. 5. A device according to claim 1, wherein the first generator delivers a voltage of 115 Vac at 400 Hz and at a power of 90 kVA when it is connected to the aircraft network. 6. A device according to claim 1, wherein the first generator delivers a power of 150 kW when it is connected to the electrical taxiing network. 7. A device according to claim 1, wherein the second generator delivers electrical power in a range of 30 kVA to 40 kVA, and a voltage of 115 Vac at 400 Hz. 8. A method of electrically powering an aircraft disposed on a ground and including an aircraft electricity network, the method comprising: a first powering an electrical taxiing network by a first electricity generator, and powering the aircraft electricity network by a second electricity generator; anda second powering the aircraft electricity network by the first electricity generator while not powering the electrical taxiing network by the first generator, and not powering the aircraft electricity network by the second electricity generator,wherein the first electricity generator delivers a first AC voltage to the electrical taxiing network during the first powering, and delivers a second AC voltage to the aircraft electricity network during the second powering. 9. A method according to claim 8, wherein the first electricity generator is a three-stage synchronous generator with wound rotor excitation, which is excited, the excitation being controlled by an electronic power unit for switching between: either an electricity generator configured to deliver the first AC voltage to the electrical taxiing network, or an electricity generator configured to deliver the second AC voltage to the aircraft electricity network, orfrom a generator configured to deliver a predetermined electrical power to the electricity generator configured to deliver the second AC voltage. 10. A device according to claim 1, wherein the electrical taxiing network includes a rectifier which converts AC voltage to DC voltage. 11. A method according to claim 8, wherein the electrical taxiing network includes a rectifier which converts AC voltage to DC voltage.
