Abstract[English]
A tap changer-based LLC converter includes a first switch network; a resonant tank including a capacitor, a first inductor, and a second inductor that provides a primary winding; a transformer with a plurality of secondary windings; and a rectifier. The plurality of secondary windings is connected to a tap changer network that select which one or more of the plurality secondary windings connect to the rectifier. The tap changer network and plurality of secondary windings enable the LLC converter to change ratios of windings as needed during operation of the LLC converter. For example, the turns ratio between the primary winding and the secondary windings can be configured from 1:1 to 1:10.[French]
Un convertisseur LLC reposant sur un changeur de prises comprend un premier réseau de commutation ; un réservoir résonant comprenant un condensateur, une première bobine d'induction et une seconde bobine d'induction qui fournit un enroulement primaire ; un transformateur ayant une pluralité d'enroulements secondaires ; et un redresseur. La pluralité d'enroulements secondaires est connectée à un réseau de changeur de prises qui sélectionne le ou les enroulements secondaires parmi la pluralité d'enroulements secondaires connectés au redresseur. Le réseau de changeur de prises et la pluralité d'enroulements secondaires permettent au convertisseur LLC de changer des rapports d'enroulements selon les besoins pendant le fonctionnement du convertisseur LLC. Par exemple, le rapport de tours entre l'enroulement primaire et les enroulements secondaires peut être configuré entre 1:1 à 1:10.
