| Abstract | A single-crystal LiNbO/sub 3/ piezoelectric transformer having a 140 degrees rotated Y-cut plate that uses the longitudinal vibration of the transverse effect was studied. The results of the equivalent circuit and analysis and experiments conducted on symmetrical devices having electrodes of the same length and asymmetrical devices having electrodes of different lengths are presented. When driven with a constant voltage, the dependence of the voltage transformation ratio on load resistance differs when the load resistance is below or above about 10 k Omega . In the low-load-resistance range, the voltage transformation ratio does not depend on the load resistance and is determined by the ratio of electrode lengths. The transformation characteristics measured closely match the calculated value when the elastic loss at the support and the floating capacitance of the electrodes are considered. A minimum resonant resistance of 9 Omega was exhibited by an element measuring 32 (L)*12 (B)*0.5 (T). The maximum transmitted power was about 1 W for a device having a 12-mm element. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
