piezoelectric ceramic transformer (solidformer®)
piezoelectric transformer (solidformer®) can generate a high voltage by
a low voltage input through the utilization of a resonance phenomenon of the
piezoelectric transducer.
the applications include high voltage power supplies,such as inverters for
liquid crystal display back-lighting, dust collectors, copy machines, facsimile
machines, ionaizer, and ozonizers.
principle
the piezoelectr ic transfor mer has pr imar y and secondar y
electrodes on the piezoelectric ceramic. the primary side is
polarized in the thickness direction and the secondary side in the
length direction. (arrow mark shows polarization direction). when
a voltage having a resonance frequency (fr), determined by the
length dimension, is input on the primary side, a strong mechanical
oscillation is generated by inverse piezoelectric effect, and a
high voltage (vo) is output from the secondary side, matching its
oscillation by direct piezoelectric effect.
