The high voltage electrostatic generator circuit diagram composed of NE555
The multi-function high-voltage electrostatic generator is based on 555, if matching with high back voltage diode and discharge brush pin, it can be used as a negative oxygen ion generator, ignition, static vacuum cleaner, or high security, etc. 555 and R1, R2, C2 form a multivibrator with non-steady state, the oscillation frequency F = 1.44 / (R1 +2 R2) C2, the argument in the figure is about 20KHZ. After boosted by the transformer T1,then it will get 20KHZ 10KV high voltage on secondary of T1, and it will be 7KV after rectified by D1, the load current can reach 50UA.   (View)
