Title (EN) DC/DC CONVERTER
(FR) CONVERTISSEUR CONTINU/CONTINU
(JA) DC/DC コンバータ
Abstract: front page image
(EN)Provided is DC/DC converter which reduces switching loss when switching elements forming a conversion circuit are switched on, and which stabilizes the conversion circuit input-side common-mode voltage. A DC/DC converter 1 comprises a conversion circuit 2, a transformer T1, a clamper circuit 5, and a control circuit 4. The conversion circuit 2 comprises 4 switching elements Q1-Q4, and converts input direct current voltage to alternating voltage voltage. The clamper circuit 5 is electrically connected between the conversion circuit 2 and a primary winding T11 of the transformer T1, and forms a closed circuit, through which a primary current I1 flows, with the primary winding T11. The clamper circuit 5 also comprises switches QC1, QC2 which open and close the closed circuit. The control circuit 4 controls the four switching elements Q1-Q4 and the switches QC1, QC2.
(FR)L'invention porte sur un convertisseur continu/continu qui réduit les pertes de commutation lorsque des éléments de commutation formant un circuit de conversion sont mis à l'état passant, et qui stabilise la tension de mode commun du côté d'entrée du circuit de conversion. Le convertisseur continu/continu 1 comprend un circuit de conversion 2, un transformateur T1, un circuit de calage 5 et un circuit de commande 4. Le circuit de conversion 2 comprend 4 éléments de commutation Q1-Q4, et convertit une tension continue d'entrée en une tension alternative. Le circuit de calage 5 est connecté électriquement entre le circuit de conversion 2 et un enroulement primaire T11 du transformateur T1, et forme un circuit fermé, dans lequel un courant primaire I1 circule, avec l'enroulement primaire T11. Le circuit de calage 5 comprend également des interrupteurs QC1, QC2 qui ouvrent et ferment le circuit fermé. Le circuit de commande 4 commande les quatre éléments de commutation Q1-Q4 et les interrupteurs QC1, QC2.
(JA)変換回路を構成するスィッチ素子がオンに切り替わる際のスイッチング損失の低減を図り、且つ変換回路の入力側のコモンモード電圧の安定化を図ることのできるDC/DCコンバータを提供する。DC/DCコンバータ1は、変換回路2と、卜ランスT1と、クランプ回路5と、制御回路4とを備える。変換回路2は、4つのスイッチ素子Q1〜Q4を有し、入力される直流電圧を交流電圧に変換する。クランプ回路5は、変換回路2と卜ランスT1の一次巻線T11との間に電気的に接続され、一次巻線T11と共に一次側電流I1の流れる閉回路を形成する。また、クランプ回路5は、閉回路を開閉するスィッチQC1,QC2を有する。制御回路4は、4つのスィッチ素子Q1〜Q4及びスィッチQC1,QC2を制御する。
