Abstract
L'invention concerne un générateur électrochirurgical (10), délivrant une tension constante et une sortie de puissance variable, particulièrement adapté à la formation d'arc de découpe à une électrode active comportant une zone de surface active dynamique à géométrie variable. La commande essentiellement basée sur une tension constante est réalisée grâce à l'utilisation d'une tension de liaison continue dont le niveau fontionne afin d'établir l'amplitude de la sortie d'un inverseur RF résonant. L'invention concerne aussi une commande de rétroaction à double boucle dans laquelle les signaux de commande basés sur la tension de sortie sont lentement introduits à faible gain, alors que les commandes de tension de liaison basées sur moteur sont comparativement rapidement appliquées. L'amélioration portant sur le développement d'une tension de liaison continue commandée est réalisée par l'utilisation d'un réseau d'entrée incorporant un étage de correction de facteur de puissance.
