| 摘要 |
The present invention relates to a thrust-reversal device for an aircraft which includes at least two thrust reversers including a cowl which is movable between a closed position and an open position, actuated by at least one actuator (5, 5') driven by at least one electric motor powered by a single power-conversion module (100, 200, 300) supplied with electricity by a single electricity source of said aircraft. The device according to the invention is characterised in that the power-conversion module includes at least one autotransformer (301) supplied with AC electric voltage by the electricity source (3) and connected to at least one rectifier stage suitable for converting said AC voltage into DC voltage, said rectifier stage being connected to a stage for balancing and/or smoothing the current which is suitable for supplying DC voltage to said electric motor (6, 6') of said actuator (5, 5') of said cowl. |
