Title (EN) MATRIX CONVERTER WITH SOLID STATE CIRCUIT BREAKER
(FR) CONVERTISSEUR MATRICIEL À DISJONCTEUR À SEMI-CONDUCTEUR
Abstract:
(EN) A matrix converter includes one or more current sensors structured to sense current flowing through the matrix converter, a matrix of switches including a number of solid state transistors, and a control circuit structured to detect faults in power flowing through the matrix converter based on the sensed current, to control the matrix of switches to drive an external device, and to control the matrix of switches to switch to prevent power from flowing internal to the matrix converter, or external to the external device in response to detecting a fault in power flowing through the matrix converter.
(FR) Cette invention concerne un convertisseur matriciel, comprenant un ou plusieurs capteurs de courant structurés pour détecter un courant circulant à travers le convertisseur matriciel, une matrice de commutateurs comprenant un certain nombre de transistors à semi-conducteur, et un circuit de commande structuré pour détecter des défauts dans l'énergie circulant à travers le convertisseur matriciel sur la base du courant détecté, pour commander la matrice de commutateurs pour exciter un dispositif externe, et pour commander la matrice de commutateurs de sorte à commuter pour empêcher l'énergie de circuler à l'intérieur du convertisseur matriciel, ou à l'extérieur du dispositif externe en réponse à la détection d'un défaut dans l'énergie circulant à travers le convertisseur matriciel.
