| Abstract | In power processing applications, switching power converter research have focused on the potential feasibility of piezoelectric transformers (PTs) for cost competitiveness, size effect and good EMI characteristics. However, the PT has a voltage conversion limit because of its physical dimensions and manufacturing procedures. The fact can be a restriction to a circuit engineer facing new application design with PT because of its in adaptivity to extreme conversion ratios of emerging applications. In order to overcome this problem, tapped inductor is introduced. The tapped inductor can transform the input voltage into the adequate level by its own turn-ratio. Consequently, this tapped inductor scheme with piezoelectric transformer makes it possible to obtain both PT's advantages and conversion gain adjustment without part-count increase. For the proposed converter evaluation, this paper provides the operation analysis and design procedures of the converter, and presents the experimental verification with a 20-W hardware prototype DC/DC converter as well. Finally, topology extension is also presented by combining tapped-inductor with other conventional resonant converters with piezoelectric transformer. |

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.
