| Abstract | A power supply with potential use in the magnetic stimulation of biological systems is presented in this paper. The effect of the magnetic stimulation depends on the geometry and orientation of the induced electric field, as well as on the current pulse waveform delivered by the stimulator (coil). These factors are very important to define the equipment requirements and characteristics, namely the topology of the power supply and the size and geometry of the coil. The proposed solution is able to generate current pulses with variable amplitude and duration, according to a user- defined input. The main characteristics and the working principle, including the strategy of control, are described. In order to design, to analyse and to verify the performance of the developed power supply, both simulation and experimental results are presented. The proposed solution is based on a topology that uses elements to store and transfer energy from the power source to the load. With the proposed topology, an adequate control strategy and right set of the power circuit parameters it is possible to obtain either unipolar waves or bipolar waves. |

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.
