    摘要: A piezoelectric transformer has pairs of input/output electrodes located on a piezoelectric body corresponding to period locations on a standing sine wave superimposed on said body, and having a waveform corresponding to vibrational modes of the piezoelectric body at resonance. The transformer also has a grounded guard electrodes to reduce parasitic coupling between its input and output regions.
