Title: Driving circuit for eield effect transistor
Inventor: SANUKI NAGATO
IPC: H03K17/04
Filed: 1986-08-25
Abstract: PURPOSE:To attain fast speed interruption by connecting the ternary winding of a transformer, a 2nd switch element and a diode in series, connecting a connecting point between the ternary winding and the diode to one terminal of a DC voltage source via a resistor and connecting a connecting point between the 2nd switch element and the diode to the other terminal of the DC voltage source. CONSTITUTION:When a switch element 6 is turned off at t=t3 and a switch element 7 is turned on simultaneously, the ternary winding n3 of the transformer 3 is short-circuited by the switch element 7 and a diode 9. Since the secondary winding n2 is short-circuited as well by the transformer action, the electric charge stored in a capacitance existing between the gate and the source of a FET 5 is discharged rapidly through the secondary winding n2. That is, the gate-source voltage of the FET 5 is made rapidly zero and the FET 5 is turned off rapidly.
