Title: Fet gate drive circuit
Inventor: WATANABE KIYOMI
IPC: H03K17/04
Filed: 1994-04-05
Abstract: PURPOSE:To drive at a high speed a switching circuit which uses an FET of large gate input capacity. CONSTITUTION:The DC voltage is charged to a capacitor 13 from a high frequency source 21 via an insulating transformer 19 and a diode 17. An FET 29 is switched on and driven via a driving transformer 3 and the diodes 5 and 7 when a drive signal source 1 generates the positive voltage. Meanwhile a transistor TR 11 is turned off. When the polarity of the source 1 becomes negative, the TR 11 is turned on by the sum of the voltage charged between the gate and the source of the FET 29 and the charged voltage or true capacitor is. Thus the TR 11 rapidly passes the zero state of the gate voltage and is set in the backward bias state. This adverse bias voltage is limited to the proper value by a Zener diode 15.
