Title
(EN) POWER CONVERTER WITH ROBUST STABLE FEEDBACK
(FR) CONVERTISSEUR DE PUISSANCE À RÉTROACTION STABLE ROBUSTE
Abstract
(EN)
Various methods and devices that involve power converter with stable feedback are disclosed. A disclosed power converter comprises an input node on an input side of the power converter and an output node on an output side of the power converter. The power converter also comprises a switch coupled to the input node and having a control node, a feedback path between the output node and the control node, and a first circuit block on the feedback path with a multipath feedback active filter. The first circuit block is at least partly defined by a pure bandpass transfer function.

La présente invention concerne différents procédés et dispositifs qui mettent en œuvre un convertisseur de puissance avec rétroaction stable. Un convertisseur de puissance de l’invention comprend un nœud d'entrée sur un côté d'entrée du convertisseur de puissance et un nœud de sortie sur un côté de sortie du convertisseur de puissance. Le convertisseur de puissance comprend en outre un commutateur couplé au nœud d'entrée et ayant un nœud de commande, un trajet de rétroaction entre le nœud de sortie et le nœud de commande, et un premier bloc de circuit sur le trajet de rétroaction avec un filtre actif de rétroaction à trajets multiples. Le premier bloc de circuit est au moins partiellement défini par une fonction de transfert passe-bande pure.
