摘要： An ON holding circuit (21-24) is provided which outputs a signal which identifies the ON state of an insulated gate transistor (10) to a gate voltage input circuit (1-9), and inhibits the gate voltage input circuit (1-9) from being responsive to the input signal which identifies the OFF state of the insulated gate transistor (10) when the adjusting operates continuously.
