| Abstract |
In this study, a disk-type piezoelectric transformer was fabricated. Its diameter was 50[㎜] and thickness was 4.5[㎜]. The driving and generating electrode with their gap of 1[mm] were fabricated on the top surface. But the common electrode was fabricated on the whole bottom surface. The electrode surface ratio of driving and generating part on the top surface was the range of 1.4:1 to 3:1. We investigated the electrical characteristics with the variation of its thickness and the electrode surface ratio of driving and generating part in the range of load resistance of 100[Ω]～70[㏀]. From the experimental results, their influence on the set-up voltage ratio were investigated quantitively and qualitatively. |
