| Abstract: | The voltage gain, output power and efficiency are three important parameters to characterize the multilayer piezoelectric transformer (MPT). In this paper, a piezoelectric transformer provided by Weihua Corp was employed for evaluation of their basic electrical properties and the influence of the environment temperature in the basic electrical properties. The results show that the environmental stability of the step-down multilayer piezoelectric transformer is good, but dramatical changers of environment in a long time will have influences on the performance, and high environment temperature also affects the use of performance seriously. |
