A muliple outputs of piezoelectric transformer based on the stress distribution

A new type of piezoelectric transformer which is based on the stress distribution of the piezoelectric transformer to change the output voltage is presented. In this paper, we verified the feasibility of the principle of the new piezoelectric transformer from the simulation and experiment. The experiment results show a good consistent with the theoretical analysis. The designed piezoelectric transformer is very capable of multiple output and the structure is simple. The proposed piezoelectric transformers can provide applications in multiple output of piezoelectric transformers of all the vibration mode.
