Abstract

Le dispositif de surveillance d’un convertisseur (22) de puissance réversible à structure résonante ou quasi-résonante destiné à être relié à un bus de tension continue et à une charge électrique, le convertisseur de puissance comprenant un pont de puissance (29) destiné à être relié en entrée au bus de tension continue, le pont de puissance comportant deux bornes (40, 46) de sortie, le pont de puissance comprenant au moins deux bras (33, 34) de commutation pour transférer de l’énergie électrique entre le bus de tension continue et les bornes de sortie, chaque bras de commutation comportant au moins deux transistors (37, 38, 42, 43) reliés en série et fonctionnant en commutation douce, chaque borne de sortie étant reliée entre les deux transistors d’un bras différent. Le dispositif de surveillance comprend des moyens de mesure de tension aux bornes du pont de puissance, des moyens de détermination de défaillance de transistors des bras de commutation, et des moyens de commande, les moyens de détermination de défaillance étant configurés pour comparer les tensions des bornes à des seuils prédéterminés pendant un temps mort lors de la commutation d’un premier transistor de l’un des bras de l’état passant à l’état ouvert, et pour déterminer si le premier transistor est défaillant en fonction du résultat des comparaisons, les moyens de commande étant configurés pour ouvrir au moins le deuxième transistor dudit bras de sorte qu’un courant ne circule pas à travers le deuxième transistor lorsque le premier transistor est défaillant. Figure pour l’abrégé : Fig 5The device for monitoring a reversible power converter (22) with a resonant or quasi-resonant structure intended to be connected to a direct voltage bus and to an electrical load, the power converter comprising a power bridge (29) intended to be connected at the input to the direct voltage bus, the power bridge comprising two output terminals (40, 46), the power bridge comprising at least two switching arms (33, 34) for transferring electrical energy between the direct voltage bus and the output terminals, each switching arm comprising at least two transistors (37, 38, 42, 43) connected in series and operating in soft switching, each output terminal being connected between the two transistors of a different arm. The monitoring device comprises means for measuring voltage at the terminals of the power bridge, means for determining failure of transistors of the switching arms, and control means, the means for determining failure being configured to compare the voltages of the terminals at predetermined thresholds during a dead time when switching a first transistor from one of the arms from the on state to the open state, and to determine whether the first transistor has failed based on the result of the comparisons , the control means being configured to open at least the second transistor of said arm so that a current does not flow through the second transistor when the first transistor is faulty.
