Abstract
A switching unit of an embodiment includes a first switching element of normally-on type, a second switching element of normally-off type having a non-reference potential side conductive terminal connected to a reference potential side conductive terminal of the first switching element, a resistive element having one end connected to a conduction control terminal of the first switching element; a series capacitor connected between the other end of the resistive element and a conduction control terminal of the second switching element; and a diode having an anode connected to the other end of the resistive element and a cathode connected to a common junction of the first switching element and the second switching element.
