Abstract
Official abstract text for this publication.
A switching circuit ( 80 ) includes: a plurality of insulated gate transistors ( 30 - 33 ) connected in parallel between a high voltage line (L 1 ) and a low voltage line (L 2 ); 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 (L 3 ), and a single capacitor is connected between the gate voltage apply line (L 3 ) and the high voltage line (L 1 ).
