In this paper. we designed and simmulated a ring-dot type piezoelectric transformer. As the result, piezoelectric transformer of 25${\times}25{\times}3.5mm$ size (Dot electrode diameter of Ilmm) show the maximum displacement, stress and output power. When the Input voltage of piezoelectric transformer was 155V. Output voltage show 30V and output power 9W at the load resistance of $100\Omega$

In this paper, we used the $BaTiO_3$ system ceramics with high temperature stability for high voltage devision, and rosen type-piezoelectric transformer for high voltage measurement. when Line-high voltage is 13,20O[V], Input voltage of piezoelectric transformer type-actuator is about 390CV1, and output voltage of it is 26.5FVI on the no-load. And also, temperature stability from >$-25^{\circ}C$ to >$50^{\circ}C$ is less than ${\pm}4.45%$
