Title
(EN) POWER TRANSFER DEVICES, METHODS, AND SYSTEMS WITH CROWBAR SWITCH SHUNTING ENERGY-TRANSFER REACTANCE
(FR) DISPOSITIFS, PROCÉDÉS ET SYSTÈMES DE TRANSFERT D'ÉNERGIE À PROTECTEUR À THYRISTOR COURT-CIRCUITANT UNE BOBINE D'INDUCTANCE DE TRANSFERT D'ÉNERGIE
Abstract
(EN)
The present application discloses methods, circuits and systems for power conversion, using a universal multiport architecture. When a transient appears on the power input (which can be, for example, polyphase AC), the input and output switches are opened, and a crowbar switch shunts the inductance which is used for energy transfer. This prevents this inductance from creating an overvoltage when it is disconnected from outside lines.
(FR)
La présente invention porte sur des procédés, des circuits et des systèmes de conversion de puissance, utilisant une architecture multiport universelle. Lorsqu'un transitoire apparaît sur l'entrée de puissance (qui peut être, par exemple, un courant alternatif polyphasé), les interrupteurs d'entrée et de sortie sont ouverts, et un protecteur à thyristor court-circuite la bobine d'inductance qui est utilisée pour un transfert d'énergie. Cela empêche cette bobine d'inductance de créer une surtension lorsqu'elle est déconnectée de lignes extérieures.
