Claim 43:
44. A method for operating a piezoelectric transformer, the method comprising:
applying an input signal by a driver circuit 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
measuring, by the field probe, at least one of the following: a pressure, a temperature, a humidity, a conductivity, an ozone concentration, a gas composition, an ion concentration or a particle concentration; and
taking into account, by the drive circuit, at least one of the following during adaptation of the input signal: the pressure, the temperature, the humidity, the conductivity, the ozone concentration, the gas composition, the ion concentration or the particle concentration.
