FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering, namely, to devices for electrically powering an aircraft on the ground, comprising two electric generators, driven by an auxiliary power unit. First generator is connected by a selective connection/disconnection mechanism to an aircraft network and to an electrical taxiing network to deliver AC voltage to the aircraft electricity network, when connected to the aircraft electricity network, or AC voltage to the electrical taxiing network, when connected to the electrical taxiing network. Second electricity generator is connected by the connection/disconnection means to the aircraft electricity network to deliver AC voltage to the aircraft electricity network, solely when the first electricity generator is powering the electrical taxiing network.
EFFECT: technical result is providing independent power supply of the taxiing network from the aircraft network without restrictions, related to the certification standards for the aircraft network.
