Abstract

The invention provides an emergency power network for aircraft, for powering actuator motors (4) connected to the network, the network comprising a power bus (11) adapted to convey three-phase AC power generated by at least one DC/AC converter (12) that is powered by a DC source of the aircraft, the converter being fitted with modulator means for modulating the voltage and/or the frequency of the three-phase power generated thereby.

Claims

1. An emergency power network for aircraft, for powering actuator motors connected to the network, the network comprising a power bus adapted to convey three-phase AC power generated by at least one DC/AC converter that is powered by a DC source of the aircraft, the converter being fitted with modulator means for modulating the voltage and/or the frequency of the three-phase power generated thereby.

2. An emergency power network according to claim 1, wherein the converter is of the linear amplification type.
