Abstract
An apparatus and a method for generating a non-thermal atmospheric pressure plasma are disclosed. In an embodiment, an apparatus for generating a non-thermal atmospheric-pressure plasma includes a first piezoelectric transformer, a second piezoelectric transformer, and a drive circuit configured to apply an input voltage to each of the piezoelectric transformers, and wherein the input voltage applied to the first transformer is phase-shifted by 90° in relation to the input voltage applied to the second transformer.
