“…The resonant radial frequencies , , are related among them as follows: (6) Equations (4)- (6) can be used to find the breakdown voltage, which occurs when the arc impedance is practically infinite, (no significant current passes through the reactor electrodes); thus, (5) is simplified to (7) from which the voltage gain is given as (8) This ratio of tension becomes high enough to reach the breakdown level when the operating frequency equals the ignition frequency ; the resultant expression depends simply on the ratio of capacitances. This equation is depicted in Fig.…”

This paper proposes a new system to ignite and to sustain a plasma discharge for different reactor configurations, using a single-series parallel high-frequency resonant converter. The different operation modes are analyzed, and their performance is verified in two applications: an equilibrium plasma discharge (electric arc) and a nonequilibrium plasma discharge (electric barrier at atmospheric pressure) with intensity current and voltage amplitude varying from 135 mA and 1050 V to 600 mA and 502 V, and operating the reactors at 60 Hz, 14 kHz, and 40 kHz. The principal features and results are remarked, such as its ease of adaptation to several regimes of discharge, by simply changing the operational frequency.Index Terms-Arc discharge, dielectric barrier discharge, equilibrium discharge, glow discharge, nonequilibrium discharge, resonant converter.

“…This work was supported in part by CONACyT (the Mexican Council for Science and Technology) under Grants 33424-U and 33797-A and in part by COSNET another to sustain the plasma state. Other converter topologies, suitable for providing the high current at low voltages, can be found in the literature [5]- [8].…”
