HV capacitors
You can buy HV caps, but they are extremely expensive.
You can choose to set some lv in serie.
Here is the formula:

Totall capacitance = (C1xC2)/(c1+c2)
2200 uF 25Volt + 2200 uF 25 Volt
Makes: 1100 MFD  50 V

if you use the same caps you can just divide the capacity of one cap by the number of caps in series.

example: 4 caps with a capacity of C1 in series, then the total capacity is C = C1/4
