Abstract

Abstract Translated from French Procédé de linéarisation des caractéristiques de sortie (tension, courant) d'un convertisseur continu-continu (1) pseudorésonant à transfert direct comprenant un condensateur d'oscillation (C) et soumis à des cycles de commande prédéterminés comprenant chacun une phase de conduction directe. Method for linearizing the output characteristics (voltage, current) of a direct transfer pseudoresonant DC-DC converter (1) comprising an oscillation capacitor (C) and subjected to predetermined control cycles each comprising a direct conduction phase . Ce procédé comporte une étape de décharge totale dudit condensateur d'oscillation (C), quel que soit le courant de sortie (IS), commencée au plus tard à l'issue de chaque phase de conduction directe, suivie immédiatement d'une étape de maintien à une valeur sensiblement nulle de la tension (VC) aux bornes dudit condensateur d'oscillation (C). Des dispositifs appliquent ce procédé. This method comprises a step of completely discharging said oscillation capacitor (C), whatever the output current (IS), started at the latest at the end of each direct conduction phase, followed immediately by a step of maintaining at a substantially zero value of the voltage (VC) across said oscillation capacitor (C). Devices apply this process. Utilisation pour les convertisseurs d'alimentation d'ordinateurs et de systèmes électroniques embarqués, de très forte puissance massique. Use for power converters for computers and on-board electronic systems, with very high specific power.
