Currently, I am selecting a power generator for Dielectric barrier discharge (DBD) reactor. I am wondering between 02 devices: AC sinusoidal power generator or Pulse power generator. Which power supply device provides the best performance on the DBD reactor? And in accordance with the method of calculating discharge power DBD using V-Q curve Lissajous (Because I currently have high voltage probes 1000x and monitor capacitors. I don't want to use the high current probe to calculate the discharge power for some reason I don't have this device right now)
If I want to change both voltage V and frequency F for DBD reactor, I need to choose which power supply device. Please suggest me some specific power generator supplies.
I sincerely thank you and wish all the best!
Dear Ha Khanh Hop
Please take a look at these sites.

They have different power supplies which produce high voltage and high frequency, I have been using one of that power supplies to operate DBD plasma actuators.
Regarding to the use of Lissajous curve to obtain the electrical parameters is a quite accurate method, for me there is no need of using current probes which are extremely expensive. You can also use the current resistor method (placing a resistor in series with the DBD device) to obtain the current waveform and once more no need of buying a current probe.
we use Nanjing Suman power supply for a long time , it can change voltage and carrier frequency and pulsed frequency
Dear Dr Borui Zheng !
I was a little concerned because the power supply CTP-2000K (Nanjing Suman Co. LTD) applies only to the plasma reactor with a discharge gap no more than 8 mm. I want to use plasma equipment with discharge gas of about 10-15 mm, whether CTP 2000K is suitable?
Finally, I sincerely thank Dr's answer. I hope to continue to receive your help.

Do you mean large area or large scale of plasma discharge? If so, you can try to use the sliding discharge , then you can get an larger area of plasma discharge, it is easy to above 20 mm in width.
Dear Dr Borui Zheng
I hope Sir well
Thank Sir for your repply.
I mean is the CTP-2000K device of Nanjing Suman company suitable for cylindrical DBD reactor with a large discharge gap of about 10-15 mm? Because, as I know, Nanjing Suman company recommends that their products CTP-2000K should be applied with a discharge gap of about 8 mm.
Can Sir send me some sliding discharge's documents? I have not had the conditions to research it.
Thanks again!
Hi, i hope you already find a good one.
the performance actually depends on the application. for the specs, you may want to check frequency, voltage range, power etc. this is also related to you reactor. most of the product on the market does have the function to change voltage and frequency. for the electrical diagnostic, this paper may be helpful:

wish you success.
