Line voltage negative half-cycle trigged high voltage pulse generator - This
circuit generates high voltage pulses from 230vac line voltage. The drive end's swing
comparator circuit is invented by the creator of this page. The work end is derived
from stroboscope trig supply circuit. All line voltage using circuits are inherently
dangerous, and this is particulary so. Do not build it. (added 06/09)

Low Power 12,000 Volt Power Supply - If you need about 12,000 volts DC for
an ion generator this circuit might be the ticket. It draws power from the 120vac
power line but it uses a small 6KV camera flash trigger coil. The output signal is
isolated from the power line. Although the circuit can only deliver about 5uA of
current it can produce dangerous shocks, so be careful.... [Designed by David A.

Negative Ion Generator #2 - The design of the Negative-Ion Generator is
fairly straightforward (see Fig. 1). The circuit is a high voltage generator. It
contains a standard 555 timer that's used to generate square-wave pulses. The pulses
are applied to the base of the TIP120 NPN Darlington transistor. The Darlington
provides sufficient current to the base of the 2N3055 power transistor to turn it on.

Solid-State Tesla Coil, #1 - Nikola Tesla is considered by some to be the
greatest inventor of our modern electrical age, and many experts consider him to be
the true father of radio. However, today he is best remembered for his fascinating
wireless power-transmission experiments, using his famous Tesla Coil. The
high-frequency air-core, oscillating Tesla Coil is just as exciting today as it was
back in 1899.... [rewritten by Tony van Roon] |

Solid-State Tesla Coil, #2 - Tesla coils have been around for almost 100
years and, with th exception of vacuum-tube driven coils, not much has changed from

coil: a true solid-state Tesla coil. One thing that makes our Tesla coil unusual is
that the coupling to the secondary coil is by a direct electrical connection rather
than by magnetic fields.... [rewritten by Tony van Roon] |

Square Tesla Coil - Figure 1 shows the schematic diagram of the Tesla Coil
circuit. The circuit consists of little more than a few coils, a step-up power
transformer, and a capacitor. Power from an AC wall receptacle is fed to transformer
T1 (a small neon-sign transformer) which steps the voltage up to about 3000-volts
AC.…. [Tony van Roon's circuit] |

Super Cheap 1500 Volt Power Supply small Laser Supply - This little power

transformer is wired backwards. 9V windings connect to 120V(circuit / schematic design

Tesla Coil/H Volt Generator (Aaron Cake) - This is a fun and useful circuit
for demonstrating high frequency high voltge. It can produce up to about 30KV,
depending on the transformer used. It is cheap and easy to make, thanks to the
standard TV flyback transformer used. It can power LASERS (although I have never
tried), demonstrate St.Elmo's fire, and even cause a fluorescent bulb to light from as
much as 2 feet away. |
