              What is piezoelectric transformers ?

Piezoelectric transformers are made by using the piezoelectric effect of the conversion of electrical energy and mechanical energy. They consist of two parts by input and output. Their polarization of piezoelectric ceramic rings is perpendicular to each other. The input is polarized in the thickness direction, after the alternating voltage is applied. For longitudinal vibration, due to the inverse piezoelectric effect, pickup piezo transducer will have a high voltage output.

The piezoelectric ceramic transformer is a new type of solid-state electronic device. Compared with the traditional electromagnetic transformer, piezoelectric generator has a simple structure, small size, light weight, and variable pressure Large-scale, piezo sphere sensor is good stability, no electromagnetic interference and high efficiency, high energy density, high safety, no winding, non-combustible, no leakage magnetic phenomena and electromagnetic radiation pollution, etc. Based on the working mode of the piezoelectric ceramic transformer, piezoelectric vibration sensor can be divided into the following categories,it is rosen-type piezoelectric ceramic transformers, piezoelectric vibratory, piezoelectric ceramic transformers and radial vibration mode piezoelectric ceramic transformers, etc.

In recent years there have been some better piezoelectric transformers, such as two input terminals. Third-order vibration mode has piezoelectric ceramic transformer and high-power multilayer piezoelectric ceramic transformer. Currently piezoelectric ceramic transformer is mainly used as AC-DC, DC-D C ，piezoelectric power generationcan be used for other power devices and high voltage generating devices, such as liquid crystal displays in the cold cathode tube, neon tube, laser tube and small X-ray tube, it is high voltage electrostatic spraying, high voltage electrostatic flocking and radar display tube drive.
