What happens if you use Tesla coil to charge a capacitor?

Click For Summary

Discussion Overview

The discussion centers around the feasibility and implications of using a Tesla coil to charge a capacitor in order to achieve a high DC voltage output with low current. Participants explore theoretical aspects, safety concerns, and practical considerations regarding component ratings and personal experience with high voltage systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification
  • Safety-related

Main Points Raised

  • One participant inquires about the possibility of using a Tesla coil to charge a capacitor and the effects of high capacitance on the output.
  • Several participants raise concerns about the availability of rectifier diodes and capacitors that can withstand the high voltages produced by a Tesla coil.
  • Questions are posed regarding the participant's background with high voltage and the intended application of the setup.
  • Another participant emphasizes the potential dangers of working with high voltages without sufficient experience and suggests seeking mentorship.
  • A later reply discusses the theoretical implications of high capacitance, noting that it could lead to higher peak currents through the diode, while also acknowledging the idealized nature of this discussion.
  • One participant reiterates the importance of safety and suggests that the discussion may not be suitable for those with limited experience.

Areas of Agreement / Disagreement

Participants express concerns about safety and the technical feasibility of the proposed setup, but there is no consensus on the practicality or safety of using a Tesla coil in this manner. Multiple competing views on the risks and theoretical aspects remain unresolved.

Contextual Notes

Limitations include the lack of specific details regarding component ratings, the potential dangers associated with high voltage, and the assumptions made about ideal components versus real-world applications.

I am trying to create a high DC voltage output(with extremely low current output).

I thought of something like this. The left coil would be the tesla coil. Can I use this to charge the capacitor and create high DC voltage? What would happen if capacitance was really high?

Welcome to PF.
Where will you get a rectifier diode with sufficient reverse voltage rating.
Where will you get a capacitor with a sufficient voltage rating.
Do you know what voltages you are going to encounter?
 
Welcome to the PF. :smile:

What's the application? What's your background with high voltage?

Will the voltage be built up to a very high level?(if the diode and capacitor can withstand, of course)
I know the voltage output from tesla coil is very high.
I don't have much experiece with high voltage. I want to know the theory and the potential danger.

then you should be finding who lives in your area that can mentor you directly
you shouldn't be playing with very high voltages on your own when you have little experience

Well, if you're speaking from a purely ideal point of view and completely disregard safety and part acquisition I can help with the "What would happen if capacitance was really high?" portion of your post. Other members, please feel free to correct me because I will learn from it as well.

The bigger your output capacitance the higher the peak current your diode will see. Since we're assuming perfect parts this won't matter but in reality it can make a difference.
