Abstract
A switching circuit according to one embodiment includes: a switching element that has a first terminal and a second terminal, and is driven by a pulse signal to switch a conduction state between the first and second terminals; a power source section that supplies a voltage to the first terminal; a load circuit that is connected in parallel with the power source section; a passive circuit section that is connected between a connection point between the power source section and the load circuit, and the first terminal, and suppresses a current flowing from the connection point to the switching element at a frequency N times (N is an integer of 1 or more) as high as a clock frequency of the pulse signal; and a resonant circuit section that is connected between the passive circuit section and the connection point, and resonates at the frequency of N times.
