PURPOSE:To reduce tune-on loss, by connecting a diode between the gate terminal and the source terminal of a FET, and connecting the gate terminal and the source terminal to a driving signal source via a resistor. CONSTITUTION:A diode 5 is connected between the gate terminal G and the source terminal S of the FET4 in a direction where forward directed voltage drop by a reverse voltage for the FET4 becomes less than the threshold voltage of the FET4, for example, in the direction where the cathode of the diode is directed toward the gate terminal G, and the anode toward the source terminal S if the FET is an N-channel FET. Also the gate terminal G and the source terminal S are connected to the signal driving source 1 via the resistor 3 and a pulse transformer 2. |
