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.
