Drive circuit for switching element and switching circuit

A gate drive circuit that is connected to a gate terminal and a source terminal of a first switching element and turns on and off the first switching element, the gate drive circuit comprising:

• a controller that comprises a first terminal connected to the gate terminal and a second terminal connected to the source terminal, comprises a first switch provided between the first terminal and a voltage source, and a second switch provided between the first terminal and the second terminal, and is configured to switch between the first switch and the second switch to control turning on and off of the first switching element;
• a first resistor and a first capacitor, each having one end connected to the gate terminal and another end connected to the first terminal, the first resistor and the first capacitor being connected in parallel to each other;
• a second capacitor that has one end connected to the source terminal and another end connected to the second terminal;
• and
• a first Zener diode that has a cathode terminal connected to the source terminal and an anode terminal connected to the second terminal, and is connected in parallel to the second capacitor.
