| Abstract: | According to properties that piezoelectric transformer required, the possibilities of improving mechanical quality factor, electrical quality factor, electromechanical coupling factor and temperature stability of resonant frequency of multi-system ceramics are analyzed from the aspects of morphotropic phase-boundary (MPB), composite ceramics, acceptor dopants and transient liquid-phase sintering. The rules of designing ceramics for piezoelectric transformer are proposed. |
| Keywords: | piezoelectric transformers piezoelectric ceramics designing rules |
