DBD dielectric barrier discharge

Output voltage frequency pulse width adjustable with overvoltage overcurrent and other protection functions digitization customization available

DBD plasma is a non-equilibrium gas discharge that occurs between two electrodes, at least one of which is covered with an insulating medium such as ceramic or glass. When high-frequency AC or pulse voltage is applied, the gas is ionized under the influence of the electric field, forming micro-discharge channels and generating active particles such as electrons, ions, and free radicals. The insulating medium limits the current, prevents the formation of arcs, and ensures stable and uniform discharge. The medium can also store charge and maintain discharge when the voltage reverses. DBD is widely used in ozone generation, surface treatment, waste gas purification, and biomedical fields, with the core being the medium's control over discharge, ensuring efficient and safe non-thermal plasma generation.
