Abstract[English]
A flux-modulated electromagnetic apparatus includes an induction machine including a rotor and a stator surrounding the rotor. The rotor includes a core and a rotor winding including a plurality of metal bars in contact with an outer surface of the rotor or an outer surface of the core. The stator includes slots, a power winding, a first control winding and a second control winding. The flux-modulated electromagnetic apparatus includes a first voltage source converter electrically coupled to the stator having a first AC terminal and a first DC terminal and a second voltage source converter electrically coupled to the stator having a second AC terminal and a second DC terminal. The first DC terminal is electrically coupled to the second DC terminal via a capacitor. The first AC terminal is electrically coupled to the first control winding. The second AC terminal is electrically coupled to the second control winding.[French]
La présente invention concerne un appareil électromagnétique à modulation de flux qui comprend une machine à induction comprenant un rotor et un stator entourant le rotor. Le rotor comprend un noyau et un enroulement de rotor comprenant une pluralité de barres métalliques en contact avec une surface externe du rotor ou une surface externe du noyau. Le stator comprend des fentes, un enroulement de puissance, un premier enroulement de commande et un second enroulement de commande. L'appareil électromagnétique à modulation de flux comprend un premier convertisseur de source de tension couplé électriquement au stator ayant une première borne CA et une première borne CC et un second convertisseur de source de tension couplé électriquement au stator ayant une seconde borne CA et une seconde borne CC. La première borne CC est électriquement couplée à la seconde borne CC par l'intermédiaire d'un condensateur. La première borne CA est électriquement couplée au premier enroulement de commande. La seconde borne CA est électriquement couplée au second enroulement de commande.
