    Hello!
    I am progressing with my project, I now have finished my 240w DC HV power supply. I'm having some trouble understanding a equation on Richie Burnett's site, it should calculate the required value of a capacitor however I cannot managed to use it even for the given example. I'm sure this is a shortcoming of my own but any help will be greatly appreciated in understanding it.
    The following is from his site, I'll add a link and the formula as shown.

    Design a DC resonant charging circuit to process a maximum power of 8kW. The highest rotary speed will be 500 BPS, and a 10kV DC supply will be used to power the system.
    What values of Charging Inductor and Tank Capacitor should be used to meet this specification ?
    The tank capacitor value is found by substituting Pmax, BPSmax and Vdc into the second from last equation to get:
    Cp = 80 nF
    ( the equation result is said to be in farads)
