Abstract

L'invention concerne un onduleur en pont à puissance réglable et à rendement amélioré aux différentes puissances. Les thyristors montés en pont avec des diodes parallèles tête-bêche sont commandés par un oscillateur donnant une fréquence dite de répétition, qui est au maximum les deux tiers de fréquence de l'onduleur. On fait varier la puissance en agissant sur la fréquence de répétition asservie à la puissance affichée. Possibilité d'obtention d'un fonctionnement de l'onduleur en fréquence basse, égale au tiers de la fréquence nominale haute. Application au chauffage par induction.
