The proposal “SafePEM” followed the aerospace industrial trend to foster “More Electric Aircraft” in order to improve the control of energy and finally reduce the fuel consumption by reduction of weight and more effective use of resources. SafePEM will significantly improve currently existing Power System Control due to offering the provider of such system an increased flexibility of design using a deterministic approach for the Power Control System internal data communication system implementing an innovative “Power Control Manager”. This approach implemented a robust, reliable and scalable system architecture allowing the implementation in many aircraft platforms at minimised modifications required. Thus, time for modifying the design was saved resulting in cost reduction and finally offering an opportunity to reducing the price of the system. As a consequence, supplying such novel system improved competitiveness compared to competing systems.

On the other end, the new design approach allowed to handle today’s required high-power density which is not possible satisfactory when relying on technologies and solutions available. The architectural approach allowed managing several “Power Electronics Modules” in layer one (Power Electronics Layer). Multiple electronic loads can be driven and required currents are supplied according to demands.

A dedicated second layer was in charge of controlling all resources and providing the distribution of data to all participants of the network in a reliable manner. It incorporated two bus systems ensuring safe data communication with appropriate supervision on the one hand and safe communication between the PEMs on the other hand.
