Piezoelectric transformer

Abstract

In an embodiment a plasma generator includes a piezoelectric transformer having an input region and an output region, wherein the input region is configured to convert an applied AC voltage into a mechanical oscillation, wherein the output region is configured to convert the mechanical oscillation into an electrical voltage, wherein the piezoelectric transformer is configured to ignite a plasma at an output-side end side of the piezoelectric transformer, 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.
