Plasma Generation using Dielectric Barrier Discharge

Click For Summary

Discussion Overview

The discussion revolves around the generation of plasma using Dielectric Barrier Discharge (DBD), focusing on the challenges of creating a suitable power source from a standard 220 V/50 Hz AC supply. Participants explore the necessary voltage and frequency requirements, as well as the equipment and methods needed for their experiments.

Discussion Character

  • Technical explanation
  • Homework-related
  • Experimental/applied

Main Points Raised

  • One participant expresses difficulty in determining the required voltage and frequency for DBD plasma generation from a standard AC socket.
  • Another participant recalls using an induction coil for generating ozone through a silent discharge method in a glass tube during their school days.
  • There is a request for links to resources on DBD and its applications, indicating a need for more information on the topic.
  • One participant emphasizes the need for the plasma to sustain for a considerable amount of time for their experiment.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific methods or calculations needed to generate plasma using DBD, and multiple viewpoints and requests for information remain unresolved.

Contextual Notes

Participants have not provided specific calculations or detailed methods for generating the required voltage and frequency, leaving gaps in the discussion regarding the technical requirements for DBD.

I am having trouble in making a power source for the DBD. I can't seem to find any calculations to get the required voltage and frequency of AC to generate plasma. I want to know the circuit/method/equipment needed to generate that voltage from a normal 220 V/50 Hz AC socket in my lab.I am doing it as an experiment for my second year undergraduate project.
Thank you

Welcome to the PF. :smile:

Can you post some links to DBD? What applications is it used for?

When I was at school we used an induction coil and we used the discharge for making Ozone. The discharge took place through the wall of a glass tube, and we called it a Silent Discharge at that time.
 
I need the plasma for an experiment. I want it to sustain for a considerable amount of time.

Okay, but that doesn't really help much. Could you please address my question/request? Thanks.
