The FET is part of a MOSFET push-pull driver which is driving a capacitive load. The load charges up as the gate charges, keeping the gate-source voltage within safe limits. Here's an earlier design that I've tested at +/- 50 V:
The diodes at the input make the MOSFET gates straddle the input...
Splitting voltage across BJTs to avoid breakdown
Hi,
I'm trying to use a BJT bipolar totem pole to drive a MOSFET gate to an arbitrary voltage, similar to this:
However, I am working with +/- 240 V, driving gate capacitances of over 10nF at ~1 MHz, which requires up to 4.5A and hundreds of...
