    How do i get 250v dc power supply??
    Should I use lots of batteries or is there an easier way?

    You will have to tell us much more if you want a sensible answer. What do you need this power supply for? What will you be doing with the generated voltage? What amperage do you need? For how long? Do you have access to mains power? How clean must the 250v be?

    I am using this to charge a capacitor bank containing 5 250v 180uF capacitors.I have access to mains power.This is not for injuring anyone. It is not intended to cause harm.

    250 volts DC doesn't care whether you intend to cause harm - it's quite capable of deciding to hurt someone all by itself. And .8 milliFarads at that voltage? You're building something as inherently dangerous as a chainsaw... And you wouldn't be asking the question you did if you had the background and experience to do this safely.

    Sorry, I'm locking the thread.
