Abstract:
1. A switching circuit, comprising: N switching elements having respective one ends and respective control terminals, where N is an integer of 2 or more; a connection circuit including N−1 first inductance elements connected in series, wherein the control terminals are connected to a plurality of nodes of the connection circuit, respectively, and the nodes include contacts of the first inductance elements and input and output terminals of the connection circuit; a second inductance element having one end and an other end, the one end of the second inductance element being connected to a DC power supply; and third inductance elements connected between the other end of the second inductance element and the one ends of the switching elements, respectively, wherein the switching elements are switched sequentially by a PWM signal that is input to the input terminal of the connection circuit.
