Abstract
A plasma reactor comprises a working chamber, the chamber being adapted to receive at least one article and a volume of plasma which is capable of interacting with a material of the article. A pair of electrodes are positioned about the chamber. Further, a radio-frequency generator is provided. More particularly, the plasma reactor includes a radio-frequency voltage transformer. The transformer includes a primary winding that is connected to the generator and a secondary winding the center of which is grounded. The secondary winding is adapted to transform the energy received from the primary winding into plasma-exciting energy at the electrodes, whereby the voltage between the plasma and the ground is small such that voltage discharge between the plasma and any grounded parts is minimized.
