Abstract: A treatment pad for a dielectric barrier discharge plasma treatment of a tissue to be treated of an electrically conducting body, which tissue is used as a counter electrode, said treatment pad comprising: a treatment zone, arranged for at least covering the tissue to be treated; a pattern of one or more active areas, integrated in the treatment zone and arranged for generating a dielectric barrier discharge plasma, each said one or more active areas comprising: a first electrode to be coupled to a high voltage power source; a dielectric formed by a coating or foil of a flexible material so that the dielectric shields the first electrode from the tissue to be treated; and a spacer comprising a structured surface of protrusions adjacent a side of the dielectric facing the tissue to be treated; wherein the treatment zone comprises a complementary pattern of non-active areas, such that a complementary part of the tissue to be treated is covered by the said one or more active areas when the treatment pad is reapp

Abstract: The invention relates to a high voltage source to be coupled to an electrode arrangement for a dielectric barrier discharge plasma treatment. It has a high voltage transformer device including a primary and secondary inductor coupled via a magnetic circuit. A feed circuit including a power capacitor, the power capacitor coupled with the primary inductor and a first controllable conductor in series. A controller is arranged to intermittent switching of the first controllable conductor in on- and off-states; and a second controllable conductor is coupled in parallel to the primary windings; the controller arranged to switch the second controllable conductor to a conducting on-state when the first controllable conductor is in an on-state to short the resonating current in the primary inductor.

Abstract: An electrode arrangement is described that is configured to be coupled to a high voltage source for a dielectric barrier discharge plasma treatment of an irregularly three-dimensionally shaped surface of an electrically conducting body. The three-dimensionally shaped surface is used as a counter electrode. A first planar electrode is coupled to the high voltage source via a first lead, fitted to the object to be treated and brought in contact with a dielectric. A second electrode is contacted with the surface to be treated as reference electrode. The second electrode is provided in an edge portion that is circumferential to the first planar electrode and configured to be coupled to a reference voltage source via a second lead. An isolating cover layer covers the electrode and a third electrode covers the isolating cover layer as a ground electrode.
