Title: Method for driving mosfet
Inventor: SEKINE MASAOKI
IPC: H03K17/691
Filed: 1988-03-07
Abstract: PURPOSE:To control switching speed, to suppress the rise of a voltage and a current and to omit or miniaturize a snubber circuit by controlling the gate driving current of a MOSFET. CONSTITUTION:When an on-pulse is impressed from a pulse transformer P11 for transmitting an on-pulse, a large current flows through a Zener diode ZD1 into the gate of the MOSFET. When a gate voltage rises and approaches a threshold voltage, the ZD1 is turned off, the driving current is rapidly reduced, and the current is made into only a small constant current supplied from a transistor TR1. For such a reason, even at the time of conducting, the rise of a drain current is made gentle. When a drain voltage starts to be lowered and it is lowered down to a set voltage, a transistor TR2 is conducted, a gate current is increased again, the gate voltage is made to rapidly rise, the MOSFET is completely saturated, and it is turned on. Thus, the rise of the voltage and current can be suppressed, and the snubber circuit can be omitted or miniaturized.
