| Abstract |
In this paper, a hexagon-type piezoelectric transformer was investigated to increase the output power. The length of its side was 14mm and 17.5[mm], respectively. The piezoelectric ceramics was composed to PZT-PMN-PSN. This composition showed the characteristics which had an about 1200 of the mechanical Q-factor, 0.55 of the electromechanical coupling coefficient, 320×10-12 C/N of the piezoelectric constant d33, 0.3% of the dissipation factor, etc. The voltage step-up ratio increased with increasing the load resistance, RL, so it reached 80 with RL of 1[㏁] and was proportion to the length of side of the hexagon-type piezoelectric transformer. |
