50khz Highly Output Piezoelectric Ceramics Ultrasonic Welding Transducer

Specification:

Description:

The piezoelectric ceramic transformer uses the piezoelectric effect of the polarized piezoelectric body to realize the voltage output. The input part is driven by a sinusoidal voltage signal and vibrates through the inverse piezoelectric effect. The vibration wave is mechanically coupled to the output part through the input and output parts. The output part generates electric charge through the positive piezoelectric effect to realize the electric energy of the piezoelectric body. -Mechanical energy-two transformations of electrical energy to obtain the highest output voltage at the resonance frequency of the piezoelectric transformer. Compared with the electromagnetic transformer, this has the advantages of small size, light weight, high power density, high efficiency, breakdown resistance, high temperature resistance, no fear of combustion, no electromagnetic interference and electromagnetic noise, and simple structure, easy production, and easy mass production. In some areas, it has become an ideal substitute for electromagnetic transformers. This type of transformer is used in switching converters, notebook computers, neon lamp drivers, etc.
