In order to study the effects of some parameters

such as the compensating inductance

the thickness of the dielectric layers and the size of the air gap

on the characteristics of dielectric barrier discharge

using DC power supply in series with a square wave inverter as the main circuit topology

we designed a DBD high-frequency high-voltage power supply

in which the output power and frequency of the power supply could be regulated separately. DBD discharge experiments were conducted by using single-deck and double-deck Teflon as the plasma generator. Moreover

the influences of key parameters

such as compensating inductance

dielectric layer thickness

and gap size

on the resonant frequency of discharge load circuit and discharging effect were analyzed emphatically. The results show that the resonant frequency of discharge load circuit can be regulated by changing the compensating inductance

and with the dielectric layer thickness and gap size increasing

the capacitance of the dielectric capacitor and gas capacitor decreases

the resonant frequency of discharge load circuit increases

and the discharging effect weakens.
