Abstract

Sont divulgués dans la présente demande un procédé et un appareil de commande de circuit de purge, un dispositif de purge et un dispositif électronique. Le circuit de purge comprend un premier trajet et un second trajet ; le premier trajet est relié en parallèle au second trajet. Le procédé de commande consiste à : s'il est détecté qu'une tension d'entrée du circuit de purge est réduite, commander l'activation du premier trajet ; sinon, commander la désactivation du premier trajet, lorsque le premier trajet est dans un état activé, le circuit de purge est dans un état de purge rapide, et lorsque le premier trajet est dans un état désactivé, le circuit de purge est dans un état de fonctionnement normal. Lorsqu'un circuit d'alimentation électrique est dans un état de fonctionnement normal, le premier trajet est commandé pour être désactivé, et à ce moment, le circuit de purge est dans l'état de fonctionnement normal, et une stabilisation de tension et une élimination de signal d'interférence sont réalisées dans le circuit ; lorsque le circuit d'alimentation électrique est dans un état de purge, le module de commande commande l'activation du premier trajet, de telle sorte que le processus de purge du circuit d'alimentation électrique est accéléré.
