Claim 35:
36. A method for operating a piezoelectric transformer, the method comprising:
applying, by a driver circuit, an input signal to the piezoelectric transformer;
measuring a field strength of an electric field produced by the piezoelectric transformer by a field probe at a measurement point;
adopting the input signal applied to the piezoelectric transformer while taking into account measurement values; and
transmitting the input signal to evaluation electronics,
wherein the evaluation electronics detects a load arranged in front of an output end side of the piezoelectric transformer with aid of a change in the field strength, and
wherein the driver circuit is configured so that a power sufficient for an ignition of a nonthermal atmospheric pressure plasma is applied to an input region of the piezoelectric transformer only when the load is detected in front of the output end side.
