Title (EN) CONSTANT CURRENT FAST CHARGING OF ELECTRIC VEHICLES VIA DC GRID USING DUAL INVERTER DRIVE
(FR) CHARGE RAPIDE À COURANT CONSTANT DE VÉHICULES ÉLECTRIQUES PAR LE BIAIS D'UN RÉSEAU DE DISTRIBUTION DE COURANT CONTINU EN UTILISANT UN CIRCUIT D'ATTAQUE À DOUBLE ONDULEUR
Abstract:
(EN) A switching circuit for controlling charging input from a DC source to at least one inverter circuit, each inverter circuit corresponding to at least one respective battery, the switching circuit is provided with a switching device which when positioned in series with the inverter circuit and the DC source, the switching device configured to control the charging input provided to the at least one respective battery, the switching device controllable in conjunction with switches in the at least one inverter circuit based on at least one voltage of the at least one respective battery.
(FR) L'invention concerne un circuit de commutation destiné à commander une entrée de charge depuis une source de courant continu vers au moins un circuit onduleur, chaque circuit onduleur correspondant à au moins une batterie respective. Le circuit de commutation est pourvu d'un dispositif de commutation qui, lorsqu'il est positionné en série avec le circuit onduleur et la source de courant continu, est conçu pour commander l'entrée de charge fournie vers ladite batterie respective. Le dispositif de commutation peut être commandé conjointement avec des commutateurs dans ledit circuit onduleur sur la base d'au moins une tension de ladite batterie respective.
