The preparation process of Ozone based on dielectric barrier discharge is the most effective method, and highly efficient power is the key to the preparation process. As the merits of piezoelectric transformer are high-frequency, high step-up and no electromagnetic pollution relative to the electromagnetic transformer, it is particularly suited to the ozone generator. A laminated circuit piezoelectric...
Piezoelectric transformer (PZT) is a device which transforms voltage by piezoelectric effect and converse piezoelectric effect of ceramic material. Compared with electromagnetic transformer, it has favorable characteristics of miniaturization, electromagnetic-noise free and the variable voltage gain with frequency and impedance. The modeling of piezoelectric transformer is the base of control and...
Maximum-efficiency tracking control applied in the backlight module is proposed in this paper. The backlight system incorporates a phase-locked loop as a feedback mechanism to promote both the system efficiency and stability. To overcome the drawbacks of the conventional electromagnetic transformer and miniaturize the backlight module, the piezoelectric transformer is adopted for driving the cold...
