The cap I'm charging is a 225 uF 15kV cap. It will have a 5 MOhm energy
dissipation resistor, 500W 5 kOhm current limiting resistor, and a string
of balanced diodes to perform half-wave rectification. The input power
will come from a 110 input 0 to 130 Volt out variable transformer. The
variable transformer is to be raised at a certain rate to keep the power
from being initially too high. The circuit has been designed and
simulated in pSpice. I believe the charge time was 20 or 30 seconds, I
forgot the exact number. The only missing part was a transformer.
