How can I charge my capacitor bank without a 330v DC power supply?

[AdityaDev]

I have a capacitor bank (20x 330v 180uF capacitors in parallel). But i don't have 330v DC power supply to charge the capacitors to 330 volts. I tried using a 13.7v supply from an AC adapter, but the capacitors got charged only to 13.7v. What should i do for this?Should i use another capacitor for charging?if so,how?

We closed your other thread for safety reasons when it was five 180uF capacitors and 250 volts - and here it is twenty capacitors and 330 volts. You do not have the experience and knowledge needed to do this safely.
