There is disclosed a control apparatus (12) for a power supply system (2) operable at a fluctuating line voltage, the system further comprising an energy storage device (10), and the control apparatus further comprising a line voltage monitor (14) and an energy storage device controller (12), wherein the control apparatus is configured whereby the energy storage device is at least partly discharged if the line voltage falls below a first predetermined voltage and the energy storage device is at least partly charged if the line voltage exceeds a second predetermined voltage and in which the first predetermined voltage is substantially lower than the second predetermined voltage. A power supply system (12) incorporating such a control apparatus is disclosed, as is a method of control thereof.
L'invention porte sur un régulateur (12) d'alimentation (2) pour tensions de ligne fluctuantes comportant un dispositif (10) de stockage d'énergie, un analyseur (14) de tension de ligne, et un contrôleur 12 du dispositif de stockage d'énergie. Ledit régulateur est tel que le dispositif de stockage d'énergie se décharge au moins partiellement si la tension de ligne s'abaisse au-dessous d'un premier seuil prédéterminé, et se charge au moins partiellement si la tension de ligne s'élève au-dessus d'un deuxième seuil prédéterminé, la première tension prédéterminée étant sensiblement plus basse que la deuxième tension prédéterminée. L'invention porte également une alimentation (12) incorporant ledit régulateur et sur don procédé de commande.
