Title:
ＤＣ／ＤＣコンバータ及びその制御方法
Document Type and Number:
Japanese Patent JP6846762
Kind Code:
B2
Abstract:
To achieve a higher voltage during stepping-up and a smaller voltage during stepping-down, in executing switching using a control signal with the same duty ratio as that of a conventional circuit.SOLUTION: The DC-DC converter includes: a transformer having primary winding connected with an input voltage source through a primary line and secondary winding connected with a capacitor connected to an output terminal through a secondary line; a first switch provided on the primary line and connecting/disconnecting the primary line; a second switch provided on the secondary line and connecting/disconnecting the secondary line; a third switch forward connecting or disconnecting the input voltage source with/from the secondary winding; and a control circuit for controlling the first switch, the second switch and the third switch.SELECTED DRAWING: Figure 2
