Schematic Diagram : 1000 Volt DC to DC Regulator Circuit
Input voltage from high voltage DC DC converter is 12V AC at 800mA current and then converted to DC through a bridge rectifier Diode 1A. The voltage output of converter circuit can be adjusted in the range of 0-1000V DC. This high voltage DC DC converter uses the transformer as a base and several other active components include 555 timer IC, CMOS IC 4001, IC voltage regulator 7805, some NPN transistors and a pair of logic MOSFET IRF510 as a final amplifier.
The workings of high voltage DC to DC converter is the same principle as written in previous articles. The difference shown is this converter schematic is a high output voltage and can be arranged.
If a particular transformer mentioned in the schematic is not available, every transformer with primary specification 117V AC, 6.3V AC CT secondary to work. In this case, converter circuit operating at a sweet spot of the transformer, you may need to select a different drive frequency.
Be careful when handling high voltages! You are responsible for yourself.
