| Abstract: | Piezoelectric ceramic transformer is a new kind of electronic transformer which has low electromagnetic interference, big power density, high transfer efficiency, small in size and light in weight, no noise etc, and these characteristics are superior to traditional electromagnetic transformer. This paper summarizes the capability and the application of piezoelectric ceramic transformer and puts forward two methods of design about the power supply with low output voltage. One is to use the small transfer ratio at resonant frequency; other is use the small transfer ratio at non-resonant frequency. |

| Keywords: | piezoelectric ceramic transformer converse piezoelectric effect resonance frequency transfer ratio |
