Abstract
A switching circuit () includes: a plurality of insulated gate transistors (-) connected in parallel between a high voltage line (L) and a low voltage line (L); gate resistors (-) each provided for one of the plurality of insulated gate transistors (-) and each including a first terminal connected to a gate electrode of each of the insulated gate transistors (-); and a single gate voltage application unit () configured to apply pulsing gate voltage to the gate electrode of each of the insulated gate transistors (-) via the gate resistors (-). A second terminal of each of the gate resistors (-) provided for each of the plurality of insulated gate transistors (-) is connected to the gate voltage application unit () via a gate voltage apply line (L), and a single capacitor is connected between the gate voltage apply line (L) and the high voltage line (L).
