Aircraft power system

A power converter for use with a fan engine for an aircraft, wherein the power converter comprises:

• an electric-motor interface for electrical connection to an electric motor configured to be mechanically coupled to a driveshaft of the fan engine;
• an inverting electric-motor power stage, having a DC side and an AC side, wherein the AC side of the electric-motor power stage is electrically coupled to the electric-motor interface;
• a thrust-reverser interface for electrical connection to an electric actuator of the fan engine for actuating a thrust reverser surface of the fan engine;
• an inverting thrust-reverser power stage, having a DC side and an AC side, wherein the AC side of the thrust-reverser power stage is electrically coupled to the thrust-reverser interface;
• a DC electrical connector comprising a positive voltage terminal and a negative voltage terminal for electrical connection to a DC bus of the aircraft;
• and
• circuitry that electrically couples the positive and negative voltage terminals of the DC electrical connector to the DC side of the electric-motor power stage and to the DC side of the thrust-reverser power stage.
