Piezoelectric Ceramic Transformer Using Piezoelectric Lateral Effect on Input and on Output

Recently, the authors have investigated the characteristics of many piezoelectric ceramic materials for high-power use. As a result, some advanced materials suitable for high-power ultrasonic devices have been identified. Using these materials, new piezoelectric transformer designs different from Rosen's design can be utilized for high-voltage supply. In this paper, a piezoelectric transformer using piezoelectric lateral coupling on Input and on output is presented and simulated transformer characteristics are shown.
