Abstract

Le convertisseur ultrasonore (1) est disposé dans un circuit oscillant parallèle (4) où il oscille librement avec sa fréquence propre. De brèves impulsions d'énergie sont appliquées au circuit oscillant (4) pour maintenir l'oscillation libre. En mesurant l'allure de la tension, on obtient la fréquence d'oscillation du convertisseur (1) et on l'utilise pour la régulation de l'application en phase des impulsions d'énergie.
