Abstract
(EN)
The present invention is provided with: power supply circuits configured so as to be capable of supplying and cutting off power in correspondence to each phase; motor control circuits provided in correspondence to each phase; and full-bridge inverters (INV1 to INV3) provided in correspondence to each phase and supplied with power for driving a motor from the power supply circuits. In the event a failure occurs in any one of the three phases, the motor drive is continued by the power supply circuits, the motor control circuits, and the full-bridge inverters corresponding to the two phases other than the phase determined to be faulty.
(FR)
La présente invention comprend : des circuits d'alimentation électrique conçus de façon à pouvoir assurer et couper l’alimentation électrique en correspondance avec chaque phase ; des circuits de commande de moteur disposés en correspondance avec chaque phase ; et des onduleurs en pont complet (INV1 à INV3) disposés en correspondance avec chaque phase et alimentés en électricité pour entraîner un moteur à partir des circuits d'alimentation électrique. En cas de défaillance lors de l'une quelconque des trois phases, l'entraînement du moteur est poursuivi par les circuits d'alimentation électrique, les circuits de commande du moteur et les onduleurs en pont complet correspondant aux deux phases autres que la phase déterminée comme étant défectueuse.
