Piezoelectric transformer |
摘要 |
A piezoelectric transformer includes strip form electrodes on opposing upper and lower surfaces of a piezoelectric ceramic plate formed by screen printing using a conductive paste. By using strip form electrodes, discharge of a driving portion during polarization, degradation of reliability of mechanical strength due to excessive stress in a power generating portion during polarization, and instability of transformer output due to breakage of the electrode is prevented.
