| Abstract | A five-phase six-leg switching power amplifier was designed for five degrees of freedom (5-DOF) magnetic levitation bearing system. This amplifier carries characteristics of small size and simple control. This study analyzes its structural composition and operating principles. The control of 5-DOF magnetic levitation bearing was achieved through combination of hardware and software control, i.e. the common bridge legs utilized the maximum current error control method; whereas the load bridge legs adopted the sample-hold modulator. In order to verify its rationality and correctness, the simulation software MATLAB was used. The output current waveform at speed of 6000 r/min was plotted. The experimental results show that the amplifier has excellent overall performance to meet the requirements of actual applications. |

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.
