Abstract | Modeling a photovoltaic source is a necessary operation in order to track the maximum power point of the solar panels for a specific condition. Generally, solar panels are modeled as nonlinear elements because of their nonlinear characteristics. Thus, maximum power point is tracked by numerical algorithms. As a different approach, this paper proposes an analytical maximum power point tracking (MPPT) technique using a dynamic Thevenin model dependent on ambient conditions. The analytical MPPT controller includes the non-idealities of MPPT circuit for the duty cycle calculations. Moreover, this technique is suitable for any power source that can be modeled as Thevenin equivalent circuit. Theoretically calculated duty cycle equations for maximum power point are verified with experimental results and it is observed that they are in good agreement. Proposed analytical solution provides a faster performance comparing to numerical controllers. |

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.
