Title: Mos fet drive circuit
Inventor: KAGAYA ISAMU
IPC: H03K17/691
Filed: 1984-09-21
Abstract: PURPOSE:To attain the titled circuit with wide dynamic/static control range and to miniaturize a pulse transformer capacity for insulation by using an impulse gate drive pulse, not a rectangular gate drive pulse. CONSTITUTION:When a control pulse input is kept to a low level, a transistor (TR)4 is turned off, a TR2 is turned on and a TR3 is turned off, and the input waveform is impulse as shown in a waveform A by a differentiation circuit comprising a capacitor 19 and a resistor 8. This voltage is dropped by a Zener voltage of a Zener diode 22 through a pulse transformer 16 and the result is charged to the gate of an MOSFET. When the control pulse input is at a high level, the waveform is a negative impulse waveform to the waveform A, and the voltage is subtracted by the Zener voltage of a Zener diode 21, and the gate of the MOSFET is charged negatively. The gate voltage of the MOSFET is shown as a waveform B. In this method, even when the ratio of ON/OFF is changed suddenly, the maximum value and the minimum value of the waveform B are constant, and the MOSFET is not damaged. Further, the transformer capacity is made very small.
