Ignition Coil High Voltage Generators

Below is the schematic to a high voltage generator using one ignition coil. It runs fine on 6 volts, but you can change the 5 relay to a 9 or 12 volt relay, and run it on 12 volts. The average output (depends on the coil, the input voltage, etc…) is 40kV.

Double Ignition Coil High Voltage Generator
This next design is similar to the one above, but uses two coils with their primaries in parallel (but the + on one is to the - on the other and vice versa) and their secondaries in series. Th ...
Ignition Coil High Voltage Generator by SCR Trigger
When making the voltage doubler (if thats what your using, but this goes for every other option too) you should use photo flash capacitors. This is because they are designed for a rapid discha ...
Ignition coil driver by IC 555 + 2N3055
Here is a very simple circuit that will provide high voltage (15-40kV) sparks using a common ignition coil. The input is 12VDC at around 5 to 6 amps. Mine produces sparks that are about 3/4" t ...
High Voltage mini power supply by 2N2222
This be Mini high voltage generator at my friend wants. Because of use the transistor 2 pcs only just,build small-sized easy good. By this circuit gives pulse Generator 220V from 9V batte ...
Efficient flyback driver by IC 555 + IRF510
This is a good and fairly efficient flyback driver circuit. All parts can be obtained easily from Radio Shack, including the MOSFET. This circuit uses a 555 timer IC to pulse a 2N2222 with squ ...
