High Voltage Power Supply Circuits

12kv High Voltage Generator  -  The hobby circuit below uses an unusual method to generate about 12,000 volts with about 5uA of current.  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 . . .

2uS Light Pulse Receiver  -  Although the LF357 is an obsolete part, this circuit gives you an idea how to build a sensitive modulated light detector with high ambient light immunity.  The first section uses a 100mH inductor as an efficient photodiode current to voltage conversion circuit . . .

Nitrogen Spark Generator  -  Nitrogen or air sparks are very powerful light sources that produce flashes that last only a few nanoseconds.  This line powered circuit generates a continuous series of very small sparks across electrodes with a 0.05 inch gap . . .
