Title (EN) CIRCUITS AND METHODS PROVIDING THREE-LEVEL SIGNALS AT A SYNCHRONOUS BUCK CONVERTER
(FR) CIRCUITS ET PROCÉDÉS FOURNISSANT DES SIGNAUX À TROIS NIVEAUX AU NIVEAU D'UN CONVERTISSEUR DÉVOLTEUR SYNCHRONE
Abstract:
(EN) A circuit including: a three-level buck converter having: a plurality of input switches and an inductor configured to receive a voltage from the plurality of input switches, the plurality of input switches coupled with a first capacitor and configured to charge and discharge the first capacitor; a second capacitor at an output of the buck converter; and a switched capacitor at an input node of the inductor, wherein the switched capacitor is smaller than either the first capacitor or the second capacitor.
(FR) La présente invention concerne un circuit qui comprend : un convertisseur dévolteur à trois niveaux qui comporte : une pluralité de commutateurs d'entrée et une inductance conçue pour recevoir une tension à partir de la pluralité de commutateurs d'entrée, la pluralité de commutateurs d'entrée étant couplés à un premier condensateur et conçus pour charger et décharger le premier condensateur; un second condensateur à une sortie du convertisseur dévolteur; et un condensateur commuté à un nœud d'entrée de l'inductance, le condensateur commuté étant plus petit que le premier condensateur ou le second condensateur.
