Abstract

La présente invention concerne un générateur d'ultra-sons. Ce générateur est caractérisé en ce que l'oscillateur est alimenté en parallèle par un générateur de courant constant 4 et un générateur de tension 5 et des moyens sont prévus pour bloquer le générateur de tension 5 tant que l'impédance de la charge reste inférieure à un seuil réglable, si bien que l'alimentation fonctionne en générateur de courant constant, et au contraire à bloquer le générateur de courant constant 4 dès que l'impédance de la charge dépasse le seuil réglable, si bien que l'alimentation fonctionne alors en générateur de tension et limite la puissance de sortie. Utilisable en dentisterie.
