Title (EN) ADJUSTABLE SPEED DRIVE WITH INTEGRATED SOLID-STATE CIRCUIT BREAKER AND METHOD OF OPERATION THEREOF
(FR) EXCITATION À VITESSE RÉGLABLE COMPRENANT UN DISJONCTEUR À SEMI-CONDUCTEURS INTÉGRÉ ET PROCÉDÉ DE FONCTIONNEMENT ASSOCIÉ
Abstract:
(EN) A power conversion circuit (50) having a solid-state circuit breaker (76, 78) integrated therein is disclosed. With a disconnect switch between a utility source and the power conversion apparatus described for meeting UL489, the power conversion circuit includes an input connectable to an AC source, a rectifier circuit (56) connected to the input to convert an AC power input to a DC power, and a DC link (64) coupled to the rectifier circuit (56) to receive the DC power therefrom. The rectifier circuit (56) comprises a plurality of phase legs (62) each including thereon an upper switching unit (76) and a lower switching unit (78), wherein at least one of the upper and lower switching units (76, 78) on each phase leg (62) comprises a bi-directional switching unit that selectively controls current and withstands voltage in both directions, so as to provide a circuit breaking capability that selectively interrupts current flow through the rectifier circuit, while maintaining original power conversion functionalities.
(FR) L'invention concerne un circuit de conversion d'énergie (50) pourvu d'un disjoncteur à semi-conducteurs (76, 78) intégré. Un commutateur de déconnexion situé entre une source utilitaire et l'appareil de conversion d'énergie étant décrit pour satisfaire UL489, le circuit de conversion d'énergie comprend une entrée pouvant être connectée à une source CA, un circuit redresseur (56) connecté à l'entrée afin de convertir une entrée de courant CA en un courant CC, et une liaison CC (64) couplée au circuit redresseur (56) afin de recevoir le courant CC de ce dernier. Le circuit redresseur (56) comprend une pluralité de branches de phase (62) pourvues chacune d'une unité de commutation supérieure (76) et d'une unité de commutation inférieure (78), l'unité de commutation supérieure et/ou inférieure (76, 78) sur chaque branche de phase (62) comprenant une unité de commutation bidirectionnelle qui commande sélectivement le courant et résiste à la tension dans les deux directions, de manière à fournir une capacité de coupure de circuit qui coupe sélectivement la circulation de courant dans le circuit redresseur, tout en maintenant des fonctionnalités de conversion d'énergie d'origine.
