Improving voltage follower circuit for high voltage pulse
What I’m doing:
I have some unknown resistive loads that I want to apply an exponential decay pulse to.
Regardless of the resistance of the load, I want to be able to specify the pulse peak voltage ...

What circuit allows me to drive positive kV level pulses to antennas and over spark gaps to earth ground?
Ideally I would like 0-6kV pulses with adjustable frequency, but I could settle for 4kV and 40kHz.
Pulses should be sharp as possible. Someone suggested a PWM module with a mosfet inside and to drive ...
