Abstract:
(EN) The present invention addresses the problem of providing a DC-DC converter that can suppress output voltage fluctuation while executing dead time changing control for reducing the switching loss of the DC-DC converter, and a power supply system provided with the DC-DC converter. A DC-DC converter according to the present invention is provided with: an input terminal; an output terminal; a plurality of switch elements; and a control circuit that controls dead times among the switch elements, the DC-DC converter being used for a power supply system which includes a device different from the DC-DC converter, wherein the control circuit changes at least one dead time among the switching elements, on the basis of operation information of the device different from the DC-DC converter.
(FR) Le problème décrit par la présente invention est de fournir un convertisseur CC-CC qui peut supprimer une fluctuation de tension de sortie tout en exécutant une commande de changement de temps mort pour réduire la perte de commutation du convertisseur CC-CC, et un système d'alimentation électrique pourvu du convertisseur CC-CC. Un convertisseur CC-CC selon la présente invention comprend : une borne d'entrée ; une borne de sortie ; une pluralité d'éléments de commutation ; et un circuit de commande qui commande des temps morts parmi les éléments de commutation, le convertisseur CC-CC étant destiné à un système d'alimentation électrique qui comprend un dispositif différent du convertisseur CC-CC, le circuit de commande changeant au moins un temps mort parmi les éléments de commutation, sur la base d'informations de fonctionnement du dispositif différent du convertisseur CC-CC.
(JA) 本発明の課題は、DC-DCコンバータのスイッチング損失を低減するデッドタイム変更制御を行いながら、出力電圧変動を抑制可能なDC-DCコンバータおよびこれを備えた電源システムを提供することにある。本発明に係るDC-DCコンバータは、入力端子、出力端子と、複数のスイッチ素子と、前記複数のスイッチ素子間のデッドタイムを制御する制御回路とを備え、当該DC-DCコンバータとは異なる装置が存在する電源システムに用いられ、前記制御回路は、前記DC-DCコンバータとは異なる装置の動作情報に基づいて、前記複数のスイッチ素子間の少なくとも一つのデッドタイムを変更するDC-DCコンバータである。
