PROBLEM TO BE SOLVED: To provide a switching converter capable of extending a control range of an output voltage.SOLUTION: A DC-DC converter 10 includes a first and a second main switches Sm1, Sm2; a first and a second sub switches Ss1, Ss2; a transformer 14; a capacitor 12 for partial pressure; a first and a second reactors 16a, 16b; a first and a second rectification elements Sr1, Sr2; and a smoothing capacitor 18. With such a configuration, by on-off operating each of the main switches Sm1, Sm2, each of the sub switches Ss1,Ss2 and each of rectification switches Sr1, Sr2, a control range of an output voltage of the DC-DC converter 10 is extended. |
