28KHZ 300W Industrial Ultrasonic Spot Welder Transducer Converters For Plastic Parts Welding System

ultrasonic plastic welding transducer piezoelectric ceramic transformer uses the piezoelectric effect of polarized piezoelectric body to achieve voltage output. The input part is driven by a sinusoidal voltage signal, which generates vibration through the inverse piezoelectric effect. The vibration wave is mechanically coupled to the output part through the input and output parts, and the output part generates charges through the positive piezoelectric effect, realizing the two transformations of electrical energy mechanical energy electrical energy of the piezoelectric body, and obtaining the output voltage at the resonant frequency of the piezoelectric transformer. Compared with the electromagnetic transformer, it has the advantages of small size, light weight, high power density, high efficiency, resistance to breakdown, high temperature, no fear of combustion, no electromagnetic interference and electromagnetic noise, simple structure, easy production, easy mass production, and becoming an ideal replacement element of electromagnetic transformer in some fields. These transformers are used for switching converters, laptops, neon lamp drivers, etc.
