Title
(EN) SWITCHING STRATEGY FOR INCREASED EFFICIENCY OF POWER CONVERTERS
(FR) STRATÉGIE DE COMMUTATION POUR AUGMENTER L'EFFICACITÉ DE CONVERTISSEURS DE PUISSANCE
Abstract
(EN)
Systems and methods for operating a power converter are provided. A DC to AC converter can include an inner converter and an outer converter. The inner converter can include an isolation transformer a first plurality of switching devices. The outer converter can include a second plurality of switching devices. A control method can include determining an output voltage of the outer converter. The control method can further include controlling operation of the inner converter based at least in part on the output voltage of the outer converter.

La présente invention concerne des systèmes et des procédés d'exploitation d'un convertisseur de puissance. Un convertisseur CC/CA peut comprendre un convertisseur interne et un convertisseur externe. Le convertisseur interne peut comprendre un transformateur d'isolation et une première pluralité de dispositifs de commutation. Le convertisseur externe peut comprendre une seconde pluralité de dispositifs de commutation. Un procédé de commande peut consister à déterminer une tension de sortie du convertisseur externe. Le procédé de commande peut en outre consister à commander le fonctionnement du convertisseur interne sur la base, au moins en partie, de la tension de sortie du convertisseur externe.
