Rosen Type Piezoelectric Transformer with High Efficiency

摘要

1. The art that the invention described in the claims ; The present invention relates to a high-efficiency halogen-type piezoelectric transformer will,. ; 2. SUMMARY The present invention ; to be Solved by the invention, forming a hole in the center of the disk-shaped piezoelectric member, and the difference in capacitance value between the electrode installed on the inner surface of the hole to input and output up to by having the, same time as the step-up and pressure characteristics are both improved, and relieve the mechanical stress is concentrated at the center of the drive when the disk-shaped piezoelectric member of the piezoelectric body, for fixing the piezoelectric member to facilitate, Rosen-type piezoelectric transformer to provide the high efficiency that there is a purpose. ; 3. Subject matter of the invention of Solution ; The present invention, in the Rosen-type piezoelectric transformer, high efficiency, the diameter and thickness of the disk-shaped having a predetermined size, the size of the disk-shaped having a predetermined diameter in the center a cylindrical hole is formed, the piezoelectric ceramic material having; An input electrode disposed along the inner surface of the hole; The input electrode and the isolated interval to maintain a constant, the output electrode disposed on one surface of the piezoelectric body; And maintaining said input electrode and insulating certain intervals, so as to overlap with said output electrode, said comprising a common electrode disposed on the other surface of the piezoelectric substance. ; 4. An important use of the invention ; The present invention is a portable device such as information and communication yiyongdoem.
