Abstract:
A method for frequency control of a piezoelectric transformer and a circuit arrangement including a piezoelectric transformer are disclosed. In an embodiment, the method includes exciting a piezoelectric transformer on an input side with an AC voltage of predetermined frequency as input voltage, capturing a phase information for an input impedance of the piezoelectric transformer in a feedback path, evaluating the captured phase information in respect of a predetermined phase criterion, and regulating the frequency of the AC voltage on a basis of the evaluated phase information.

Claim (Index 18):
The circuit arrangement according to  claim 17 , wherein the detector comprises a phase detector arranged such that an signal of the input voltage is applied to a first input of the phase detector and a signal proportional to an input current on the input side of the piezoelectric transformer is applied to a second input of the phase detector, and wherein the phase detector is configured to output an output signal that comprises the phase information of the input impedance at an output.
