Electronic circuitry, power converter, and power conversion apparatus

A power converter comprising:

• a half-bridge circuit including two switching elements;
• and
• a first drive circuit and a second drive circuit configured to respectively control the two switching elements in accordance with a control signal instructing turn-on or turn-off,
• wherein each of the first drive circuit and the second drive circuit includes:
• an arithmetic circuit configured to perform an operation based on a physical quantity corresponding to a time rate of change of an output current of the switching element controlled by the drive circuit;
• a timing detection circuit configured to detect, based on a calculation result of the arithmetic circuit, a first timing and a second timing later than the first timing in a transition period of the turn-on or the turn-off;
• a current supply circuit configured to supply a drive current to the switching element in accordance with a command value of the drive current to be supplied to the switching element;
• and
• a controller configured to switch a drive current value specified by the command value to a first current value in response to the first timing, and switch the drive current value to a second current value in response to the second timing.
