Title (EN) METHOD OF CONTROLLING PARALLELED PASSIVE FRONT-END RECTIFIERS WITH AND WITHOUT INTERLEAVING
(FR) PROCÉDÉ DE COMMANDE DE REDRESSEURS FRONTAUX PASSIFS EN PARALLÈLE AVEC ET SANS ENTRELACEMENT
Abstract:
(EN) Embodiments herein relate to a method of controlling a three-phase paralleled passive front-end drive connectable to a three phase alternating current power source. The method includes connecting a coupling reactance to the rectifier bridge, the coupling reactance configured to transfer power from the rectifier to a first direct current (DC) bus, coupling the first DC bus to a second DC bus, and connecting a first inverter to the first DC bus and connecting a second inverter to the second DC bus. The method also includes connecting a first controller to the first inverter and the second inverter, the first controller configured to generate control signals to cause the first inverter and the second inverter to generate a plurality of motor excitation signals respectively, and combining the plurality of motor excitation signals from the first inverter with the plurality of motor excitation signals from the second inverter.
(FR) Des modes de réalisation de l'invention concernent un procédé de commande d'un circuit d'attaque frontal passif en parallèle triphasé pouvant être connecté à une source d'alimentation en courant alternatif triphasé. Le procédé comprend la connexion d'une réactance de couplage au pont redresseur, la réactance de couplage étant configurée pour transférer de l'énergie du redresseur à un premier bus à courant continu (CC), connecter le premier bus CC à un deuxième bus CC et connecter un premier onduleur au premier bus CC et connecter un deuxième onduleur au deuxième bus CC. Le procédé comprend également la connexion d'un premier contrôleur au premier onduleur et au deuxième onduleur. Le premier contrôleur est configuré pour générer des signaux de commande destinés à amener le premier onduleur et le deuxième onduleur à générer respectivement une pluralité de signaux d'excitation de moteur, et combiner la pluralité de signaux d'excitation de moteur provenant du premier onduleur avec la pluralité de signaux d'excitation de moteur provenant du deuxième onduleur.
