SUMMARY

The discussion focuses on creating a high voltage spark using a 24V supply voltage, specifically through the use of inductive kickback. A flyback transformer topology is recommended for generating the high voltage spike necessary to ignite the spark gap. The energy released at the spark is directly related to the energy stored in the transformer prior to the switching element's activation. This method is particularly useful for mechanical engineers venturing into electrical applications.

PREREQUISITES
  • Understanding of inductive kickback and its applications
  • Familiarity with flyback transformer topology
  • Basic knowledge of energy storage in inductors
  • Experience with switching elements like transistors
NEXT STEPS
  • Research the design and operation of flyback transformers
  • Learn about inductive kickback circuits and their applications
  • Study energy storage principles in inductors
  • Explore the use of transistors in switching applications
USEFUL FOR

Electrical engineers, mechanical engineers transitioning to electrical projects, hobbyists interested in ignition systems, and anyone looking to generate high voltage sparks safely.

Dear electrical engineers,

I'm a mechanical engineer and I tried building a capacitance ignition system which didn't work does anybody know what the easiest way is to create a high voltage spark??

My supply voltage is 24 volt.
I just need to press a button and ignite my experiment.

The easiest way is to use inductive kickback. Have you learned how to use an inductor to store energy in a current and convert it to a high voltage?
 
NO sorry I'm not an electrical engineer.
The trick will be that we need to know how much energy will be released at the spark
 
This wikipedia link should get you going. You would basically use a flyback topology tranformer to generate the high voltage spike that jumps the spark gap. The energy in the arc is similar to the energy that is stored in the transformer right before the main switching element (transistor or points) opens up.
