Abstract
A DC-DC converter using a plurality of transformers capable of decreasing the loss, preventing heat generation of transformers, and improving the heat transfer property of the core, and an integrated type transformer used in this DC-DC converter. A terminal Tin which a negative electromotive force is generated and a terminal TRin which a positive electromotive force is generated, while a switching element Qis conducting, are connected at a node N. An output coil Land output terminals TOand TOare provided on a current route shared by transformers Tand T. Diodes Dand Dare respectively inserted in a forward direction from a node Ntoward a terminal TRand in a forward direction from the node Ntoward a terminal TR. An operation of a first transformer and an operation of a second transformer are respectively assigned to a flyback operation and a forward operation.
