Abstract

In an embodiment a method includes applying an AC voltage to an input region, converting, by the input region, the AC voltage into a mechanical oscillation, converting, by an output region, the mechanical oscillation into an electrical voltage and igniting a plasma at an output-side end side of an piezoelectric transformer, wherein the piezoelectric transformer includes the input region and the output region, wherein the piezoelectric transformer includes a longest edge and a shortest edge, and wherein the longest edge has a length that is twenty times a length of the shortest edge or less.
