More Information
Summary: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.
