Piezoelectric transformers have the advantages of high power density, high stepup ratio and good stability, etc. However, their applications are limited due to the obvious temperature effect, large gap between the theoretical and practical performances. This paper specially designed a driving controller based on FPGA, maximized the converted efficiency and the voltage ratio of the piezoelectric transformer. Besides, the WiFi wireless module for realtime monitoring and control circuit of the piezoelectric transformer was also developed. The system realized the thermal performance analysis, friction loss analysis and long lifespan via the requirements of the realtime monitoring, the demand can be remotely controlled, which provides a new approach for research and monitoring components.
