Abstract:
Piezoelectric transformers are new solid-state electronic devices. They have the advantages of simple process, small volume, light weight, no electromagnetic noise, no electromagnetic winding, no inflammation, good integrity and low cost. Piezoelectric transformers have been widely used in cold cathode, neon light tube; laser light, X-ray tube, high voltage static spraying, high voltage static flocking, and radar display screen. The current research status of piezoelectric transformers is reviewed, their applications are outlined, the difficulty in developing piezoelectric transformer is stressed, and the development trend is analyzed and predicted.
