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 $100\Omega$
