Zusammenfassung:	An active clamp DC-DC converter includes a transformer having a primary coil and a secondary coil, a main switching device connected in series to the primary coil of the transformer so that the main switching device and the primary coil are connected in parallel to a DC power source, a reset capacitor, a reset switching device connected in series to the reset capacitor so that the reset switching device and the reset capacitor are connected in parallel to the primary coil of the transformer, a rectifying circuit connected to the secondary coil of the transformer, a smoothing circuit connected to the rectifying circuit, and a control circuit adjusting a dead time that elapses from the time when the reset switching device is turned off until the time when the main switching device is turned on, based on a voltage across the main switching device.
