Introduction: High Voltage Adjustable Power Supply

Picture of High Voltage Adjustable Power Supply

WARNING!! THIS IS HIGH VOLTAGE AC. THIS CAN KILL YOU. ALTHOUGH SIMPLE.

Step 1: PARTS

Picture of PARTS

1 x Ignition Coil

1 x Dimmer Switch (500+ watts)

1 x 200v 15uf Film Capacitor (DON'T USE ELECTROLYTIC)

2 x High Voltage wire

Step 2: ABOUT IGNITION COIL

Picture of ABOUT IGNITION COIL

The ignition coil is commonly found in vehicles to start ignition.

The ignition coil has three terminals; one positive, one negative and one high voltage output.

It would be labelled on the ignition coil and the high voltage output is the middle of the two terminals.

Step 3: Schematic

Picture of Schematic

This is a very simple schematic. I cannot take credit for it. There are many tutorials out there, but I had a larger output.

Step 4: Test It Out!

Picture of Test It Out!

This power supply can be used for Tesla coils, Jacob ladders and many other high voltage projects. You can experiment with the capacitance to get a larger output. The higher the capacitance, the higher the voltage and current. However, if you go up to 100uf, the spark would not be continuous.
