Abstract
(EN)
There is provided a power conversion device capable of detecting an erroneous connection of an optical fiber cable by the feedback signal state difference and automatically rearranging the phase sequence only by using logical configuration of a microcomputer control unit. A drive circuit (2) driving a semiconductor element (1) includes a test signal recognition unit (31) for outputting a unique feedback signal (32) in response to a test signal (30) from a microcomputer control unit (3). The microcomputer control unit (3) includes optical fiber erroneous connection detection means (29, 33) for detecting an erroneous connection state of an optical fiber (8) according to the unique feedback signal (32). The optical fiber erroneous connection detection means compares the unique feedback signal (32) to each normal feedback signal stored in advance and detects an erroneous connection state of the optical fiber (8) if at least one of the unique feedback signal does not coincide with the normal feedback signal.

La présente invention décrit un dispositif de conversion électrique capable de détecter une connexion erronée d'un câble de fibre optique par la différence d'états des signaux de retour d'informations et de réagencer automatiquement la séquence de phase, en utilisant uniquement la configuration logique d'une unité de contrôle d'un micro-ordinateur. Un circuit de commande (2) commandant un élément à semi-conducteurs (1) comprend une unité de reconnaissance de signal de test (31) pour produire un signal de retour d'informations individuel (32) en réponse à un signal de test (30) à partir d'une unité de contrôle d'un micro-ordinateur (3). L'unité de contrôle du micro-ordinateur (3) comprend un moyen de détection de connexion erronée de la fibre optique (29, 33) pour détecter un état de connexion erronée d'une fibre optique (8) en fonction du signal du retour d'informations individuel (32). Le moyen de détection de la connexion erronée de fibre optique compare le signal du retour d'informations individuel (32) à chaque signal de retour d'informations normal stocké au préalable et détecte un état de connexion erroné de la fibre optique (8) si au moins l'un des signaux de retour d'informations individuels ne coïncide pas avec le signal de retour d'informations normal.
