Abstract
L'invention a trait à un convertisseur. Elle a pour objet un convertisseur comportant un circuit résonnant parallèle comprenant un condensateur et une bobine, un circuit de commutation comprenant un dispositif de commutation à semi-conducteur connecté pour appliquer une différence de potentiel d'une alimentation à tension continue, et des organes de synchronisation sensibles à l'oscillation du circuit résonnant pour mettre en circuit les organes de commutation pendant une fraction d'une période seulement lorsque la valeur instantanée de la différence de potentiel oscillante aux bornes de la bobine n'est pas encore inférieure à une valeur prédéterminée, pour retarder la chute de ladite différence de potentiel oscillante et injecter de l'énergie à partir de l'alimentation dans le circuit oscillant, et un circuit de charge couplé ou relié au circuit résonnant. Application : notamment à la charge de batteries d'accumulateur.
