Here is the schematic diagram of 120 V to 12KV power supply, or you may call it high voltage generator or 120V to 12KV converter. This circuit produce very high output voltage that is about 12K volt with very small current of about 5 microAmpere.
Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor through a xenon lamp trigger coil at 120 times a second.
