| 1. An electrical network of an aircraft comprising:
several main generators,
several high voltage direct current HVDC networks, each one powered by one of the generators in normal operation,
several low voltage direct current LVDC networks, each one powered by one of the high voltage direct current HVDC networks,
several converters to transfer energy from one of the high voltage direct current HVDC networks to one of the low voltage
direct current LVDC networks, the different converters being independent and isolated from each other, each converter being
dedicated to one of the high voltage HVDC networks and to the low voltage direct current LVDC network,
a load designed to be powered in normal operation by the main generators and in backup operation by one of the low voltage
direct current LVDC networks, the backup operation being put into place when at least one of the high voltage HVDC networks
is no longer powered by the associated main generator in normal operation,
in which the converters are reversible and in backup operation the load is powered in parallel by several of the high voltage
direct current HVDC networks whose energy comes from the low voltage direct current LVDC networks.
