PROBLEM TO BE SOLVED: To provide a high-efficiency DC-DC converter.SOLUTION: The DC-DC converter includes a transformer, a switching circuit provided on the primary side of the transformer, and a rectifier circuit provided on the secondary side of the transformer. The rectifier circuit includes a first rectification section that is a series connection body of a first transistor and a second transistor in which a first electrode is connected to a second electrode of the first transistor. Each of the first and second transistors has a parasitic diode connected in the forward direction between the second and first electrodes. The withstand voltage between the first and second electrodes of the first transistor is higher than that between the first and second electrodes of the second transistor. |
