Abstract
An electronic circuit includes a diode configured to carry a surge current generated by switching of a first transistor, a capacitor connected between a cathode of the diode and a control electrode of the first transistor, and a first variable impedance circuit configured to vary an impedance between the control electrode of the first transistor and a first reference voltage node according to the surge current flowing to the diode.
