New adjustment possibilities of the electrical discharge power for the non-thermal plasma reactors

In the last years the non-thermal reactors utilization has expanded from the air or solutions depollution to the treatment of plastic or metallic surfaces, and also to the biomedical applications such as sterilization or treatment of the living tissue. In order to identify the optimum conditions for the treatments is useful to adjust the operation parameters of these reactors such as electrical discharge power. This paper shows new adjustment possibilities of the electrical discharge power by modifying the parameters of the power supply, of the circuit and also of the gas flow. The opportunity of using the auxiliary electrodes is explained, specifying the optimum displacement of them for different geometries of the GlidArc reactors. The comparison between other methods and this discharge power adjustment method provides useful information in order to choose the right solution for a specific application.
