A novel structure for aeronautic DC distribution: the Mixed function for Actuation & Power Flow Control (MAPFC)

New electrical network concepts are emerging in aeronautics due to high voltage direct current networks (HVDC). These networks give some specific possibilities concerning the connections between the bus bars and the equipments. We propose here a new component for this kind of purpose that helps in solving stability problems at the network level and in supplying powerful consumers. This component, the MAPFC - mixed function for actuation & power flow control - is an AC machine connected between two inverters. The machine can be used in a traditional way - as a motor or as a generator - but also to transfer power from one DC bus to the other. We explain the principles of the MAPFC, especially the theory in the Park's domain, and some simulation results are given. We also define capabilities and limitations of the equipment.
