This paper proposes an original association of a three-phase electrical machine, here a permanent-magnet synchronous motor (PMSM) fed by two inverters, which allows to combine two different functions: actuation and power transfers between two DC buses which supply the inverters. The considered AC machine is an open-end winding PMSM allowing the connection of two inverters supplied by two different DC buses inside a high-voltage DC network. The control part of this system uses the Park’s theory not only to drive the actuator in motor as well as in generator operating modes but also to control the energy transfer from one DC bus to the other. The concept, mixing two main functions, is named MAPFC, for “mixed actuation and power flow control.” It has been particularly developed for aeronautic applications even if other application fields could be targeted. The complete modeling and operation of the system are described. Simulation studies and experimental results are presented, which are validating the proposed concepts.
