High Voltage AC to DC

Hi all,



I need high voltage DC of very small amp. So I used IC 555 to produce the fluctuating current and step up using a radio transformer to high AC voltage, to about 2Kv. How do I go about converting this high voltage AC to high voltage DC?

Yeah, sure, but then you\'ve got to buy at least four diodes, and they\'ll all need to be fast, and at least 1kV PIV. And then you\'ll probably have to load them with parallel caps and/or resistors to try to keep them balanced. If you use a single diode and choose the cap properly, that all goes away. Note: "I need high voltage DC of very small amp"
