Abstract

In this article, a multilayer piezoelectric transformer based on lead-free Mn-doped 0.94 (Bi12 Na12) Ti O3 -0.06BaTi O3 ceramics is presented. This piezoelectric transformer, with a multilayered construction in the thickness direction, is 8.3 mm long, 8.3 mm wide, and 2.3 mm thick. It operates in the second thickness extensional vibration mode. For a temperature rise of 20 °C, the transformer has an output power of 0.3 W. With a matching load resistance of 10 , its maximum efficiency approaches 81.5%, and the maximum voltage gain is 0.14. It has potential to be used in low voltage power supply units such as low power adapter and other electronic circuits.
