Abstract

L'INVENTION CONCERNE UN GÉNÉRATEUR ULTRASONORE HAUTE PUISSANCE (PAR EXEMPLE > 500 W) À UTILISER EN PARTICULIER POUR DISTRIBUER UNE ÉNERGIE ULTRASONORE HAUTE PUISSANCE À UNE CHARGE VARIABLE COMPRENANT DES FLUIDES COMPRESSIBLES. LE GÉNÉRATEUR DE L'INVENTION COMPREND UN GÉNÉRATEUR DE FORMES D'ONDE TRIANGULAIRES DE FRÉQUENCE VARIABLE RELIÉ À DES MODULATEURS DE LARGEUR D'IMPULSION. LA SORTIE PROVENANT DU MODULATEUR DE LARGEUR D'IMPULSION EST RELIÉE AUX GRILLES D'UN TRANSISTOR BIPOLAIRE À GRILLE ISOLÉE (IGBT), QUI AMPLIFIE LE SIGNAL ET QUI L'ENVOIE À UNE BOBINE UTILISÉE POUR PILOTER UN TRANSDUCTEUR MAGNÉTORESTRICTIF. DANS UN MODE DE RÉALISATION, UNE TENSION ÉLEVÉE DE 0 À 600V CC EST DISTRIBUÉE DANS LE COLLECTEUR ET DANS L'ÉMETTEUR DU IGBT, UNE FOIS QUE LE SIGNAL EST DISTRIBUÉ. LA SORTIE DU IGBT EST UNE FORME D'ONDE CARRÉE PRÉSENTANT UNE TENSION DE +/- 600V. CETTE TENSION EST ENVOYÉE À UNE BOBINE ENROULÉE AUTOUR DU TRANSDUCTEUR ULTRASONORE. CETTE TENSION CRÉE UN CHAMP MAGNÉTIQUE SUR LE TRANSDUCTEUR ET LES PROPRIÉTÉS MAGNÉTORESTRICTIVES DU TRANSDUCTEUR FONT VIBRER LE TRANSDUCTEUR EN RAISON DU CHAMP MAGNÉTIQUE. L'UTILISATION DU IGBT EN TANT QUE DISPOSITIF D'AMPLIFICATION PERMET D'ÉVITER D'AVOIR RECOURS À UN CIRCUIT DE REDRESSEUR CONTRÔLÉ AU SILICIUM (SCR), QUI EST TYPIQUEMENT UTILISÉ DANS DES TRANSDUCTEURS ULTRASONORES DE FAIBLE PUISSANCE ET QUI PROVOQUERAIT UNE SURCHAUFFE ET SERAIT DÉFAILLANT DANS UNE TELLE APPLICATION DE CHARGE VARIABLE HAUTE PUISSANCE.
