Abstract: A circuit assembly is used for controlling a piezoelectric transformer having an input capacitance in a first circuit branch. The circuit assembly also includes a second circuit branch for compensating for the input capacitance, preferably by means of a capacitive element, and a differential amplifier having two inputs. The first input is coupled to the first circuit branch and the second input is coupled to the second circuit branch.

Abstract: What is specified is a piezoelectric transformer (10) having a surface structure which has at least one protruding surface structure segment (5), wherein the piezoelectric transformer has a contour (3) and is suitable for discharging a gas in conjunction with a counter electrode (10) for generating a plasma, wherein the surface structure is configured such that the gas discharge takes place at a multiplicity of discharge initiation points (6) on the contour (3). A width of the surface structure segment (5) is smaller than the width of the piezoelectric transformer (1).
