| Zusammenfassung: | According to one embodiment, a rectifying circuit includes a diode, a switching element, a capacitor and an auxiliary winding. The diode is connected between a first terminal and a second terminal while a direction directed from the second terminal to the first terminal is a forward direction. The switching element includes a first main electrode connected to the first terminal, a second main electrode connected to a cathode of the diode, and a gate electrode connected to an anode of the diode. The auxiliary winding is magnetically coupled to an inductor. The auxiliary winding is connected to the gate electrode through the capacitor, and is connected to the second main electrode of the switching element and the cathode of the diode. |
