Title (EN) HYBRID DC CIRCUIT BREAKER AND METHOD FOR CONTROLLING
(FR) APPAREIL ET PROCÉDÉ POUR COMMANDER UN COURANT CONTINU
Abstract: front page image
(EN)A circuit breaker and method of controlling Direct Current is disclosed. The circuit breaker has a primary conduction path (202) comprising a positive temperature coefficient (PTC) device with a positive temperature coefficient of resistance and a mechanical switch (204, CB1) is connected in series with the PTC device. There is a secondary conduction path (210) with a semiconductor switch device (211, S1; 212, S2) arranged in parallel with the PTC device. The PTC device is arranged to commutate current to the secondary conduction path in response to an increase in current through the primary conduction path. The semiconductor switch device (211, S1; 212, S2) is controllable to break current flow through the secondary conduction path.
(FR)L'invention porte sur un disjoncteur et un procédé pour commander un courant continu. Le disjoncteur comprend un chemin de conduction primaire comprenant un dispositif à coefficient de température positif (PTC) ayant un coefficient de température de résistance positif, et un interrupteur mécanique est connecté en série au dispositif PTC. Il existe un chemin de conduction secondaire comprenant un interrupteur à semi-conducteur agencé en parallèle au dispositif PTC. Le dispositif PTC est conçu pour commuter le courant vers le chemin de conduction secondaire en réponse à un accroissement du courant dans le chemin de conduction primaire. L'interrupteur à semi-conducteur est commandable pour interrompre la circulation du courant dans le chemin de conduction secondaire.
