Abstract
A piezoelectric ceramic transformer made from a piezoelectric ceramic material stacked in a multilayer package which has a driving section 502 formed by alternately stacking piezoelectric ceramic layers polarized in a direction of thickness of the piezoelectric plate. The driving section 502 has internal interdigitated electrode layers 504A, 504B for causing piezoelectric vibration by a driving voltage applied to an input terminal (Vin). A first driven section 506, also made from piezoelectric ceramic layers polarized in the longitudinal direction of the piezoelectric plate, for generating a first output voltage (Vout1) at a first output by the piezoelectric vibration transmitted from the driving section 502. A second driven section 510, made from piezoelectric ceramic layers polarized in the thickness direction of the piezoelectric plate, for generating a second output voltage (Vout2) at a second output by the piezoelectric vibration transmitted from the driving section 502. Thus, a piezoelectric ceramic multilayer transformer with a multiple output is created.
