Title
(EN) TWO STAGE RESONANT CONVERTER
(FR) CONVERTISSEUR RÉSONANT À DEUX ÉTAGES
Abstract
(EN) A resonant converter comprising: a controllable current source; a resonant tank circuit coupled to the current source; and an isolated buck-type converter coupled to the resonant tank circuit, the isolated buck-type converter having an output, wherein the resonant tank circuit enables switches in the isolated buck-type converter to switch under soft-switching conditions. In some embodiments, the controllable current source is a switch-mode-type current source. In some embodiments, the isolated buck-type converter comprises a half-bridge converter. In some embodiments, the isolated buck-type converter comprises a full-bridge converter. In some embodiments, the isolated buck-type converter comprises a push-pull converter.
(FR) L'invention concerne un convertisseur résonant, comprenant : une source de courant commandable ; un circuit résonant couplé à la source de courant ; et un convertisseur abaisseur isolé, couplé au circuit résonant, le convertisseur abaisseur isolé ayant une sortie, le circuit résonant activant des commutateurs dans le convertisseur abaisseur isolé afin qu'ils commutent dans des conditions de commutation en douceur. Dans certains modes de réalisation, la source de courant commandable est une source de courant du type à découpage. Dans certains modes de réalisation, le convertisseur abaisseur isolé comprend un convertisseur en demi-pont. Dans certains modes de réalisation, le convertisseur abaisseur isolé comprend un convertisseur à pont complet. Dans certains modes de réalisation, le convertisseur abaisseur isolé comprend un convertisseur push-pull.
