彎曲振動模式壓電陶瓷升壓變壓器

Step-up transformer and the piezoelectric ceramic preparation methods, using the input and output terminals a series arrangement of the mechanical resonance of the piezoelectric ceramics in the boost output terminal and to obtain a high electric power conversion efficiency. Co-fired with integrated piezoelectric transformer were prepared, with a compact, small device size, stable performance characteristics. Suitable for miniaturization of electronic devices. The main advantages of the device: a flat rectangular parallelepiped shape of the device structure. By co-firing process, and the size of optimization techniques will generally less used to introduce the bending oscillation mode step-up transformer design. Multi-layer co-firing structure, broaden the range of input voltage regulation.
