Title (EN) UPS FOR MIXED AC AND DC LOADS
(FR) UPS POUR CHARGES EN COURANT ALTERNATIF ET EN COURANT CONTINU
Abstract:
(EN) According to one aspect, embodiments of the invention provide a UPS comprising an input to receive input AC power, a bus configured to receive backup DC power, a first output configured to provide an output AC voltage derived from at least one of the input AC power and the backup DC power, a second output configured to provide an output DC voltage derived from at least one of the input AC power and the backup DC power, a first inverter coupled between the bus and a first transformer, the first transformer coupled to the input, a second inverter coupled between the bus and a second transformer, the second transformer coupled to the first output, and a controller configured to operate the second inverter to maintain the output AC voltage above a first threshold value and to operate the first inverter to maintain the output DC voltage above a second threshold.
(FR) Selon un aspect, des modes de réalisation de l'invention concernent un UPS comprenant une entrée pour recevoir une puissance de courant alternatif d'entrée, un bus configuré pour recevoir une puissance de courant continu de secours, une première sortie configurée pour fournir une tension de courant alternatif de sortie dérivée de la puissance de courant alternatif d'entrée et/ou de la puissance de courant continu de secours, une seconde sortie configurée pour fournir une tension de courant continu de sortie dérivée de la puissance de courant alternatif d'entrée et de la puissance de courant continu de secours, un premier onduleur couplé entre le bus et un premier transformateur, le premier transformateur étant couplé à l'entrée, un second onduleur couplé entre le bus et un second transformateur, le second transformateur étant couplé à la première sortie, et un organe de commande configuré pour faire fonctionner le second onduleur afin de maintenir la tension de courant alternatif de sortie au-dessus d'une premier valeur seuil et pour faire fonctionner le premier onduleur afin de maintenir la tension de courant continu de sortie au-dessus d'un second seuil.
