Abstract
Le circuit récepteur pour bus AC de l'invention comporte, au lieu du classique transformateur d'impulsion, des condensateurs d'isolation galvanique. La récupération de la composante continue s'effectue très simplement à l'aide d'une diode convenablement polarisée. Application : récepteurs d'entrée de périphériques.
