Abstract: A power supply architecture for powering aircraft actuators includes a single-phase on-board electricity network is connected by a power supply circuit to an electric motor of an actuator, supercapacitor associated with an electronic circuit for managing the operation of the supercapacitor, and a downstream converter device for connecting to the motor. The power supply circuit includes in succession an upstream converter device for converting the voltage of the on-board electricity network into a voltage adapted to the power supply circuit downstream therefrom. The downstream converter device is reversible, so as to convert voltage both when the motor is operating in motor mode and also when the motor is operating in generator mode. The downstream converter device is arranged selectively to have a voltage-decreasing function and to have a voltage-increasing function regardless of the mode of operation of the motor.
