I am currently attempting to build a pulsed power supply that requires an 8 H inductor to produce 50 kV 17 A square pulses with widths of 100 uS. Please see the attached schematic for more details (unfortunately, the load is comprised of a gas ionizing device, thus, the resistance fluctuates quite unpredictably).
Due to the obscurely high inductance required, I have considered using a charging resistor instead. However, I am unsure of how to find the exact resistance that will be needed to match the pulse-limiting capabilities of the 8 H inductor. How many I calculate the needed resistance?
