专利汇可以提供Piezoelectric ceramic transformer with specific width to length ratios专利检索，专利查询，专利分析的服务。并且A piezoelectric ceramic transformer of the plate type having a total length 2L and width W is driven into fundamental mode, longitudinal vibration by an A.C. input, the wave length of which is lambda , that is, 2L lambda /2. When the ratio W/L falls within the range of 0.2 to 1.2 a high voltage output and a high input-to-output power efficiency are attained. Alternatively, the piezoelectric ceramic transformer referred to above is driven into second, higher harmonic mode longitudinal vibrations where 2L lambda . When the ratio W/L falls within the range of 0.05 to 0.85 the high performance referred to above is also attained.，下面是Piezoelectric ceramic transformer with specific width to length ratios专利的具体信息内容。
