Résumé : 

In this paper a voltage gain of 155 for anunloaded Rosen type piezoelectric transformer operatingat the first mode was successfully measured with aprecision of 5%. For this purpose, it was necessary toensure a good impedance matching along the measuringcircuit. Also, using the admittance circles obtained fromthe measured admittances, the PT equivalent circuitconstants were determined experimentally and foundmatching the calculated ones (model 1D). Precisions lessthan 10% have been reported.
