Discussion Overview

The discussion revolves around methods to create a high voltage spark using a 24V supply voltage, specifically in the context of building a capacitance ignition system. Participants explore various approaches and technical considerations related to generating the spark for an experiment.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using inductive kickback as a method to generate high voltage, asking if the original poster is familiar with using an inductor for energy storage and conversion.
  • Another participant emphasizes the importance of understanding the energy released at the spark, indicating a need for clarity on energy calculations.
  • A further contribution mentions using a flyback topology transformer to create the high voltage spike necessary for the spark, referencing a Wikipedia article for additional information on the concept.

Areas of Agreement / Disagreement

Participants express different levels of familiarity with electrical engineering concepts, leading to varying suggestions and approaches. There is no consensus on a single method or solution for generating the high voltage spark.

Contextual Notes

Participants do not clarify specific assumptions about the components or configurations required for the proposed methods, and there are unresolved details regarding energy calculations and the implementation of the suggested techniques.

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.
