Abstract

La présente invention se rapporte à un circuit de commande de charge/décharge de batterie à l'aide d'un micro-ordinateur qui charge en parallèle un chargeur et un condensateur à l'aide d'un micro-ordinateur programmé auparavant, et peut en même temps fournir un courant électrique à une charge et peut être utilisé comme substitut à l'électricité commerciale en cas d'urgence. A cette fin, la présente invention porte sur un circuit de commande de charge/décharge de batterie qui comprend : une unité de circuit d'alimentation électrique (100) qui fournit le courant électrique d'une source d'alimentation électrique commerciale en courant alternatif (AC, Alternating Current) de 220 V (110) dans un état normal, fournit le courant électrique d'une source de courant électrique de générateur en courant alternatif de 220 V (120) dans un état de panne de courant, et présente un premier circuit de protection (130) destiné à protéger un transformateur abaisseur de tension (210, T1) dans un état de tension anormale ; une unité de circuit de rectification (200) qui comprend le transformateur abaisseur de tension (210) pour transformer une tension élevée de 220 V en basse tension, une diode pont (220) pour transformer la basse tension alternative transformée au moyen du transformateur abaisseur de tension en une tension en courant continu (DC, Direct Current), un second circuit de protection (230) destiné à protéger des éléments de circuit d'un côté secondaire dans un état de surcharge, et un condensateur de lissage (240, C2) destiné à éliminer les composants d'ondulation sur le circuit à cause du bruit harmonique comprend le courant continu (DC) sorti de la diode pont ; une unité de circuit d'alimentation électrique constante (300) qui est raccordée entre une borne de sortie du second circuit de protection (230) de l'unité de circuit de rectification (200) et une borne de sortie (8) d'une unité de circuit d'onduleur (900) et fournit sans cesse une tension VCC au moyen d'un régulateur de tension constante (Q11), une diode (D2) et un condensateur de lissage (C5) ; une unité de circuit de commande de surveillance (400) qui reçoit la tension VCC de l'unité de circuit d'alimentation électrique constante (300) pour commander toutes les parties du circuit, et surveille et commande l'état d'une panne de courant de la source d'alimentation électrique commerciale (110) dans l'unité de circuit d'alimentation électrique (100), un état anormal d'une unité de circuit de charge/décharge de batterie (500), et les première/seconde parties de réglage de la tension de charge (710, 720) destinées à fournir de manière stable la tension à une charge (700) ; l'unité de circuit de charge/décharge de batterie (500) ayant une partie de circuit de charge/décharge de batterie (510) destinée à charger/décharger une batterie secondaire (512) selon un signal de commande de l'unité de circuit de commande de surveillance (400) et une partie de circuit de charge/décharge de condensateur (520) destinée à charger/décharger un condensateur (522) ; et une unité de circuit d'onduleur (600) qui fournit la tension VCC à l'unité de circuit de commande de surveillance (400) et fournit le courant électrique à la charge (700) par commande de la tension continue déchargée du circuit de charge/décharge de condensateur (520) de l'unité de circuit de charge/décharge de batterie (500). Par conséquent, la présente invention permet une charge simultanée et une charge indépendante, peut effectuer une fonction d'une source d'alimentation électrique auxiliaire à l'aide des caractéristiques de décharge du condensateur par rapport à la charge qui nécessite un couple d'entraînement momentané, et peut immédiatement confirmer l'état anormal.
