Title
(EN) UNINTERRUPTIBLE POWER SUPPLY
(FR) ALIMENTATION SANS COUPURE
Abstract
(EN)
An uninterruptible power supply (10) includes an input (11) and an output (13). The uninterruptible power supply may include a first power path (22) between the input and the output. The uninterruptible power supply may also include a second power path (20) between the input and the output. The second power path may include a rectifier (42) and an inverter (46). The uninterruptible power supply may also include controls (65) configured to operate the uninterruptible power supply to supply electricity to the output. In controlling the uninterruptible power supply, the controls may selectively operate in first mode by transmitting electricity from the inlet to the outlet via the first power path while operating the inverter to condition at least one characteristic of electricity at the output. The controls may also selectively operate the uninterruptible power supply in a second mode by transmitting electricity from the input to the output via the second power path.

La présente invention concerne une alimentation sans coupure (10) comprenant une entrée (11) et une sortie (13). L'alimentation sans coupure peut comprendre un premier trajet de courant (22) entre l'entrée et la sortie. L'alimentation sans coupure peut également comprendre un second trajet de courant (20) entre l'entrée et la sortie. Le second trajet de courant peut comprendre un redresseur (42) et un convertisseur continu-alternatif (46). L'alimentation sans coupure peut également comprendre des commandes (65) conçues pour faire fonctionner l'alimentation sans coupure afin de fournir de l'électricité à la sortie. Pour commander l'alimentation sans coupure, les commandes peuvent fonctionner sélectivement dans un premier mode, en transmettant l'électricité de l'entrée à la sortie via le premier trajet de courant tout en commandant le convertisseur continu-alternatif pour conditionner au moins une caractéristique de l'électricité à la sortie. Les commandes peuvent également faire fonctionner sélectivement l'alimentation sans coupure dans un second mode, en transmettant l'électricité de l'entrée à la sortie via le second trajet de courant.
