High Voltage Spark Generator
A flyback transformer circuit was built to generate high voltage sparks. By wrapping copper foil at a small distance, the sparks were able to jump across the gap, demonstrating the principle of high-voltage discharge.
Supplies
- Flyback transformer + driver circuit
- Thin copper wire
- Copper foil sheet
- 12V DC supply
- Plastic/wood supports for insulation
Setting Up the Flyback Transformer
The flyback transformer was powered using a suitable driver circuit. The high-voltage output terminal was identified, while the return ground terminal was connected for stable operation.
Electrode Setup
Copper foil was placed at a small gap from the high-voltage terminal. This foil acted as the collector electrode, catching the sparks. The distance between electrodes was adjusted until visible sparks were generated.
Testing the Sparks
When powered, the transformer created high voltage discharge across the air gap. This produced visible sparks jumping from the high-voltage terminal to the foil.
