Title
(EN) DC/DC CIRCUIT FOR UNINTERRUPTIBLE POWER SUPPLY
(FR) CIRCUIT CONTINU-CONTINU POUR ALIMENTATION ÉLECTRIQUE ININTERRUPTIBLE
(ZH) 不间断电源的DC/DC电路
Abstract
(EN) A DC/DC circuit (8) for an uninterruptible power supply, which is a bidirectional DC/DC circuit (8) and connected to a battery (B) and a bus bar. In a mains supply mode, the bidirectional DC/DC circuit (8) draws power from the bus bar and charges the battery (B), and when the mains supply is abnormal, the bidirectional DC/DC circuit (8) works in a state that the battery (B) supplies power to the bus bar. The bidirectional DC/DC circuit (8) includes an isolation transformer. The primary side of the isolation transformer is connected to a push-pull circuit or a half-bridge circuit or a full-bridge circuit, and the secondary side of the isolation transformer is connected to a push-pull circuit or a half-bridge circuit or a full-bridge circuit. The bidirectional DC/DC circuit (8) performs turn ratio switching by selecting the taps of the primary side or the secondary side of the isolation transformer for charging and discharging voltage regulation. The DC/DC circuit for an uninterruptible power supply makes the UPS system simpler and at the same time reduces the system costs.
(FR) L'invention concerne un circuit continu-continu (8) pour une alimentation électrique ininterruptible, qui est un circuit continu-continu bidirectionnel (8) et qui est connecté à un accumulateur (B) et à une barre omnibus. Dans un mode d'alimentation réseau, le circuit continu-continu bidirectionnel (8) tire du courant de la barre omnibus et charge l'accumulateur (B). Lorsque l'alimentation réseau est anormale, le circuit continu-continu bidirectionnel (8) fonctionne dans un état où l'accumulateur (B) alimente la barre omnibus en courant. Le circuit continu-continu bidirectionnel (8) comprend un transformateur d'isolation. Le côté primaire du transformateur d'isolation est connecté à un circuit push-pull ou à un circuit en demi-pont ou à un circuit en pont complet et le côté secondaire du transformateur d'isolation est connecté à un circuit push-pull ou à un circuit en demi-pont ou à un circuit en pont complet. Le circuit continu-continu bidirectionnel (8) réalise une commutation entre rapports de spires en sélectionnant les points de prélèvement du côté primaire ou du côté secondaire du transformateur d'isolation afin de réguler la tension de chargement ou de déchargement. Le circuit continu-continu pour alimentation électrique ininterruptible rend le système UPS plus simple et, simultanément, réduit les coûts du système.
