Abstract
There is provided a DC-DC converter circuit with which conduction loss between switching elements is lower than in the conventional art, which affords an increase in power conversion efficiency. A DC-DC converter circuit includes a first switching element including a first semiconductor switch and a first diode, a second switching element including a second semiconductor switch and a second diode, an inductor connected between the cathodes of the first and second diodes, and a third switching element and a fourth switching element provided so as to face in mutually opposite directions on the anode sides of the first and second diodes, wherein a first voltage supply is connected between the cathode side of the first diode and the anode side of the second diode, and a second voltage supply is connected between the anode side of the first diode and the cathode side of the second diode.
