A DC-DC converter comprises a switching circuit (10) having an input end to which an input filter circuit is connected, a smoothing filter circuit (27) consisting of a reactor (5) and a capacitor (6) and connected to the output end of the switching circuit (10), and a control section (300) performing on/off control of the switching circuit (10) by feeding back the quantity of state of the smoothing filter circuit (27). The control section (300) includes a damping control section (40) where the quantity of damping operation for regulating the quantity of state of the smoothing filter circuit (27) is calculated based on the voltage of the capacitor (6). |
