Abstract

A switching circuit (80) includes: a plurality of insulated gate transistors (30-33) connected in parallel between a high voltage line (L1) and a low voltage line (L2); gate resistors (50-53) each provided for one of the plurality of insulated gate transistors (30-33) and each including a first terminal connected to a gate electrode of each of the insulated gate transistors (30-33); and a single gate voltage application unit (60) configured to apply pulsing gate voltage to the gate electrode of each of the insulated gate transistors (30-33) via the gate resistors (50-53). A second terminal of each of the gate resistors (50-53) provided for each of the plurality of insulated gate transistors (30-33) is connected to the gate voltage application unit (60) via a gate voltage apply line (L3), and a single capacitor is connected between the gate voltage apply line (L3) and the high voltage line (L1).
