Abstract
According to one embodiment, electronic circuitry includes a first surge voltage detection circuit configured to detect a surge voltage generated due to switching of a switching device and generate a first signal indicating a first current; and a current generation circuit configured to generate a second current larger than the first current by amplifying a current in response to input of the first signal and output the second current to a control terminal of the switching device.
