A MULTI-OUTPUT COMPOSITE PIEZOELECTRIC TRANSFORMER WITH EXPANSION VIBRATION MODE

摘要

The present invention discloses a multi-output composite piezoelectric ceramics transformer with expansion vibration mode, its many features are as follows: the primary and the secondary piezoelectric ceramics assemblies with multi-output and insulation construction are laminated and bonded by polymer adhesives to form a lamination construction; the electrodes of the piezoelectric assemblies are lead out by leading-out construction to form input and output terminals, the entire insulation layers are formed by isolation layers and insulation material covered on the exterior surfaces of the piezoelectric ceramics assemblies and the electrodes leading-out construction. The strengths of the transformer include easy adjustment of parameters for the purpose of matching the primary and the secondary, high output power and high conversion efficiency. IMAGE
