Abstract

This paper proposed a new piezoelectric transformer structure based on shear vibration modes. The difficulty in the preparation of shear vibration piezoelectric transformer was minimised using the integrated structure design. The transformer working mode was determined using a finite element simulation and laser vibrometer. A transformer preparation methodology was designed, and the transformer samples were fabricated. The test results showed that by optimising the area ratio between the input and output of the piezoelectric transformer, its voltage ratio, operating frequency, efficiency, and other parameters can be adjusted. The piezoelectric transformer samples were tested at 110 kHz. The maximum variable voltage ratio and efficiency can reach 34.1 and 91%, respectively. [ABSTRACT FROM AUTHOR]
