Abstract

L'invention concerne un circuit de transmission isolé de signal analogique de tension comprenant un circuit de génération de porteuse (2), un circuit de commande en boucle fermée (3), un circuit de génération d'onde PWM (4), un transformateur d'isolation (1) et m circuits de redressement (5). Une extrémité de sortie du circuit de génération de porteuse (2) est connectée à une extrémité d'entrée positive du circuit de génération d'onde PWM (4). Une extrémité de sortie du circuit de commande en boucle fermée (3) est connectée à une extrémité d'entrée négative du circuit de génération d'onde PWM (4). Une extrémité de sortie du circuit de génération d'onde PWM est connectée à un enroulement primaire (4) du transformateur d'isolation (1). Le transformateur d'isolation (1) comprend l'enroulement primaire et m enroulements secondaires. Le iième enroulement secondaire est connecté à une iième extrémité de sortie du circuit de transmission isolé au moyen du ième circuit de redressement (5), une mième extrémité de sortie du circuit de transmission isolé est connectée à une extrémité d'entrée négative du circuit de commande en boucle fermée, et une extrémité d'entrée positive du circuit de commande en boucle fermée est connectée à une extrémité d'entrée du circuit de transmission isolé, où m≥2, et i = 1, 2, … …, m. Par rapport au mode de transmission isolé de tension analogique classique, le circuit de transmission isolé de signal analogique de tension garantit la précision de la transmission.
