Abstract: An apparatus for producing a plasma including a control circuit which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer. A hand-held device that uses the apparatus. The piezoelectric transformer is constructed of several layers. The control circuit is implemented on a circuit board, and the piezoelectric transformer is held over the circuit board by means of a region of a first end. A high voltage is applied to a second free end of the piezoelectric transformer. The plasma is produced at atmospheric pressure.

Abstract: In an embodiment a process for producing ozone includes applying an input voltage to an input area of a piezoelectric transformer so that a high voltage is generated in an output area of the piezoelectric transformer, wherein the piezoelectric transformer is operated in a pulsed manner such that phases in which the input voltage is applied to the piezoelectric transformer and phases in which the input voltage is not applied to the piezoelectric transformer alternate at regular intervals and surrounding the piezoelectric transformer with an oxygenic process gas so that the ozone is formed from the process gas by the high voltage generated in the output area.

Abstract: A piezoelectric transformer and a method for producing a piezoelectric transformer are disclosed. In an embodiment, the method includes manufacturing a main body having an input region having electrodes and a first piezoelectric material being alternately stacked one on top of the other. An output region includes a second piezoelectric material. The first piezoelectric material is polarized and a removable contact is fitted to an output-side end side of the main body, which end side faces away from the input region. A first electrical potential is applied to the removable contact for polarizing the second piezoelectric material.
