New power centre and power electronics sharing in aircraft

The rationalization of the power sources in aircraft has led to the replacement of conventional systems by electrical ones. These new architectures have given rise to new technological needs. Indeed, power electronics is necessary to control the electrical motors. The loads are mainly the compressors for the Environmental Control System that manages the pressurization and the cooling of the aircraft cabin, the pumps (fuel and hydraulic), the fans, the starting of the engine... One optimization axis is the power electronics sharing to control these loads. This paper presents a power centre mock-up that includes 8 similar power modules.
