LOW POWER 12,000 VOLT POWER
SUPPLY
designed
by David A. Johnson, Marc 27, 1999 |
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.

The high voltage pulses produced at the
secondary of the trigger coil are rectified using two 6KV damper
diodes. The voltage doubler circuit at the secondary of the trigger
coil charges up two high voltage disc capacitors up to about 12KV.
Although this circuit can’t produce a lot of current be very careful
with it. A 12KV spark can jump about 0.75 of an inch so the
electronic circuit needs to be carefully wired with lots of space
between components. |
