(EN) A CONVERTER
(FR) CONVERTISSEUR
Abstract
(EN) A wireless power transfer system and a method of operating a multilevel converter for wireless power transfer are disclosed. The wireless power transfer system comprises a multilevel converter with stack inductors that both suppress circulating currents and replace the series inductor of a tuned LCL circuit. A zero voltage switching routine for wireless power transfer is also disclosed.
(FR) Sont divulgués un système de transfert d'énergie sans fil et un procédé de fonctionnement d'un convertisseur multiniveau pour transférer de l'énergie sans fil. Le système de transfert d'énergie sans fil comprend un convertisseur multiniveau ayant des bobines d'inductance d'empilement qui suppriment à la fois les courants de circulation et remplacent la bobine d'inductance en série d'un circuit LCL accordé. Est également divulguée une routine de commutation à tension nulle pour transférer de l'énergie sans fil.
