Abstract
L'invention est relative aux onduleurs. Onduleur du type comprenant un pont redresseur à thyristors alimenté par une source alternative et relié à un pont onduleur à thyristors, fournissant en sortie une tension alternative, le pont onduleur étant commandé par un circuit de commande comprenant un circuit de mesure de la tension de sortie du pont redresseur, et un oscillateur faisant partie d'un générateur d'impulsions de commande des thyristors du pont onduleur, caractérisé par le fait que des moyens sont prévus pour que les variations de la fréquence du signal émis par l'oscillateur en fonction de la tension de sortie du pont onduleur aient l'aspect d'une ligne brisée. Application aux onduleurs.
