Experimental validation of an optimized piezoelectric transformer design with interleaving of electrodes

Interleaving of electrodes in piezoelectric transformers (PTs) consists on placing the electrodes of the secondary side in between the electrodes of the primary side or vice versa. A new configuration of interleaved electrodes was proposed and analyzed in a previous paper using models. In this paper, the experimental validation of its features is presented, showing that the interleaving of electrodes improves not only PT performance but also the whole power converter. A 20 samples batch of this new PT design has been tested, including repeatability studies which are useful to analyze the manufacturing tolerances.
