Title
(EN) A BOOST CONVERTER AND METHOD OF CONTROLLING A BOOST CONVERTER
(FR) CONVERTISSEUR ÉLÉVATEUR ET PROCÉDÉ DE COMMANDE D’UN CONVERTISSEUR ÉLÉVATEUR
Abstract
(EN) A boost converter has a main energy storage inductor and a main GaN boost switch with a node between them. A pre-charging switch is connected at the output side of the main boost switch and the inductor, between the node and an output capacitor. The pre- charging switch comprises a body diode in the forward direction from the output capacitor to the node. The output capacitor is charged by the pre-charging switch in a pre-charge phase and this provides a soft start-up to avoid large inrush currents. A third switch, which is also a GaN switch, is in series with the pre-charging switch to provide synchronous output rectification. The third switch has a body diode in a forward direction from the node to the output capacitor. In the pre-charge phase, both the boost switch and third switch are turned off whereas in a subsequent boost phase, the pre-charging switch is turned constantly on, and alternately the boost switch and the third switch are turned on and off to implement the boost conversion.
(FR) Selon la présente invention, un convertisseur élévateur comprend un composant d’induction principal de stockage d’énergie et un commutateur survolteur principal au GaN ayant un nœud entre eux. Un commutateur de précharge est connecté au côté de sortie du commutateur survolteur principal et du composant d’induction, entre le nœud et un condensateur de sortie. Le commutateur de précharge comprend une diode de corps dans le sens direct allant du condensateur de sortie au nœud. Le condensateur de sortie est chargé par le commutateur de précharge dans une phase de précharge, ce qui produit un démarrage progressif pour éviter de grands courants d’appel. Un troisième commutateur, qui est également un commutateur au GaN, est monté en série avec le commutateur de précharge pour fournir un redressement en sortie synchrone. Le troisième commutateur comprend une diode de corps dans un sens direct allant du nœud au condensateur de sortie. Dans la phase de précharge, le commutateur survolteur et le troisième commutateur sont tous deux hors tension tandis que, dans une phase d’élévation subséquente, le commutateur de précharge est constamment sous tension, et le commutateur surélévateur et le troisième commutateur sont alternativement sous tension et hors tension pour mettre en œuvre la conversion élévatrice.
