Title (EN) HIGH-BANDWITH RESONANT POWER CONVERTERS
(FR) CONVERTISSEURS DE PUISSANCE RÉSONANTS À GRANDE LARGEUR DE BANDE
Abstract:
(EN) This specification describes a device that includes a voltage-regulated DC-DC converter comprising a switching network, a resonant circuit, and control circuitry, wherein the switching network has a switching frequency. The DC-DC converter has an output impedance and the control circuitry uses a control loop to control the DC-DC converter. The control circuitry implements the control loop using: an output voltage sensor configured to sense an output voltage of the DC-DC converter; and a compensator configured to adjust operation of the DC-DC converter based on the output voltage sensed by the output voltage sensor. The DC-DC converter comprises an output impedance suppression mechanism configured to at least partially suppress increases in the output impedance of the DC-DC converter.
(FR) La présente invention concerne un dispositif qui comprend un convertisseur CC-CC régulé en tension comprenant un réseau de commutation, un circuit résonant et une circuiterie de commande, le réseau de commutation ayant une fréquence de commutation. Le convertisseur CC-CC présente une impédance de sortie et la circuiterie de commande utilise une boucle de commande pour commander le convertisseur CC-CC. La circuiterie de commande met en œuvre la boucle de commande en utilisant : un capteur de tension de sortie configuré pour détecter une tension de sortie du convertisseur CC-CC ; et un compensateur configuré pour ajuster le fonctionnement du convertisseur CC-CC sur la base de la tension de sortie détectée par le capteur de tension de sortie. Le convertisseur CC-CC comprend un mécanisme de suppression d'impédance de sortie configuré pour supprimer au moins partiellement des augmentations de l'impédance de sortie du convertisseur CC-CC.
