Comment fonctionne l'alimentation UPS :<\/p>\n\n\n\n

1. Mode de fonctionnement de d\u00e9rivation<\/p>\n\n\n\n

Lorsque le UPS en ligne <\/strong><\/u><\/strong><\/a>est surcharg\u00e9, la commande de d\u00e9rivation (manuelle ou automatique), l'onduleur est en surchauffe ou la machine est d\u00e9fectueuse, <\/u>UPS<\/strong><\/u><\/strong><\/a> convertit g\u00e9n\u00e9ralement la sortie de l'onduleur en sortie de d\u00e9rivation, c'est-\u00e0-dire directement aliment\u00e9e par le secteur. \u00c9tant donn\u00e9 que la phase de la fr\u00e9quence de sortie de l' UPS<\/strong><\/u><\/strong><\/a> doit \u00eatre identique \u00e0 la phase de la fr\u00e9quence du secteur pendant le bypass, la technologie de synchronisation \u00e0 verrouillage de phase est adopt\u00e9e pour garantir que la sortie de l'onduleur est synchronis\u00e9e avec le secteur.<\/p>\n\n\n\n

Le thyristor bidirectionnel \u00e0 commutateur de d\u00e9rivation fonctionne en parall\u00e8le, ce qui r\u00e9sout le probl\u00e8me du temps de commutation de d\u00e9rivation, permet une commutation v\u00e9ritablement ininterrompue et le circuit de commande est complexe. Il est g\u00e9n\u00e9ralement utilis\u00e9 dans les moyennes et hautes Mises sous tension<\/strong><\/u><\/strong><\/a>.<\/p>\n\n\n\n

2. Comment fonctionne la batterie<\/p>\n\n\n\n

Une fois que le secteur est anormal, l'\u00e9nergie CC stock\u00e9e dans la batterie est convertie en \u00e9nergie CA. \u00c0 ce moment, l'entr\u00e9e de l'onduleur est aliment\u00e9e par la batterie et l'onduleur continue de fournir de l'\u00e9nergie \u00e0 la charge pour qu'elle continue \u00e0 l'utiliser, de mani\u00e8re \u00e0 r\u00e9aliser la fonction de alimentation \u00e9lectrique ininterrompue<\/strong><\/u><\/strong>.<\/u><\/a><\/p>\n\n\n\n

La source d'\u00e9nergie du syst\u00e8me d'alimentation sans interruption est la batterie<\/strong><\/u><\/strong><\/a>, et la capacit\u00e9 de la batterie est limit\u00e9e, donc le syst\u00e8me d'alimentation sans interruption<\/strong><\/u><\/strong><\/a> ne fournira pas une puissance illimit\u00e9e comme le secteur. Il doit y avoir un temps limit\u00e9 pour fournir de l'\u00e9nergie<\/strong><\/u><\/strong><\/a>.<\/p>\n\n\n\n

Mini-ups<\/strong><\/u><\/strong><\/a>\u00a0sont utilis\u00e9s dans\u00a0Routeurs WiFi<\/strong><\/u><\/strong><\/a>Cam\u00e9ras de vid\u00e9osurveillance, commandes de porte, \u00e9clairage de secours, distributeurs automatiques, imprimantes d'empreintes digitales et autres produits \u00e9lectriques intelligents.<\/p>\n\n\n\n
