Abstract
(EN)
The present invention relates to electrical engineering, in particular to a regulated transistor resonant high-frequency voltage converter with excellent efficiency, high power and low in cost, which can be used in different fields, with direct and alternating high-frequency voltage output. The regulated resonant voltage converter comprises two circuits for the simultaneous flowing of direct and indirect currents of the half-bridge transistors. A method of the resonance conversion is carried out at the expense of use of the second resonant choke that consumes power from the resonant capacitor and transmits a part of power to the rectifying load. Due to the above during all modes of operation the transistors provide for commutation at zero currents and the current amplitude does not exceed the nominal value at the expense of power interchange that particularly excludes the dynamic overloads and losses.

L'invention concerne l'ingénierie électrique, et plus spécifiquement un convertisseur de tension haute fréquence résonant à transistors régulé possédant une excellente efficacité, une grande puissance et à coût réduit, lequel peut être utilisé dans différents domaines, avec une sortie de tension haute fréquence directe et alternée. Ce convertisseur de tension résonant régulé comprend deux circuits pour le passage simultané de courants direct et indirect des transistors à demi-pont. Un procédé de conversion de résonance est mis en oeuvre au détriment de l'utilisation de la seconde bobine d'arrêt qui consume la puissance du condensateur résonant et transmet une partie de la puissance à la charge de rectification. Etant donné que tout ceci a lieu durant tous les modes de fonctionnement, les transistors permettent une commutation à zéro courant et l'amplitude de courant ne dépasse pas la valeur nominale au détriment de l'échange de puissance qui exclut particulièrement les surcharges et les pertes dynamiques.
