Power management strategies in a local DC Power Distribution System of More Electric Aircraft with the help of hybrid storage and dissipation systems

The local DC Power Distribution System of More Electric Aircraft is one of the cores of the electric power transmission. Because of some unidirectional devices (diode bridge and anti-run-back diodes), the system is not totally reversible. Some storage and dissipation systems are necessary to store or/and dissipate the returned energy to maintain the DC bus voltage. Power management strategies are introduced in this paper. The development of experimental test benches is necessary to validate these strategies. In the paper, a 3 kW test bench, emulating a unidirectional source that supplies a bidirectional load with the help of a hybrid storage and dissipation system, is presented.
