Resonant power converter comprising a matched piezoelectric transformer

Kaspar Sinding Meyer (Inventor)

Research output: Patent


The present invention relates to an electronic power converter comprising a piezoelectric transformer, a drive circuit arranged to generate and provide an input voltage signal to the piezoelectric transformer, said input voltage signal comprising a burst frequency and a substantially constant excitation frequency, and a rectifier module. According to the present invention the excitation frequency is selected among a plurality of excitation frequencies in such a way that an equivalent load resistance, Req, is matched to an output impedance of the piezoelectric transformer so as to minimize power losses in the piezoelectric transformer. Moreover, the present invention relates to a method for configuring an electronic power converter.
