| Abstract | In this research, a dual surface sliding mode controller is proposed and implemented to increase robustness and speed of boost converter, its asymptotic response is proved in the presence of disturbances. In addition, a filtered mapping pulse width modulation technique is developed to attenuate the chattering problem caused by finite frequency switching. Ripple domain search (RDS), a precise maximum power point tracking (MPPT) algorithm, is suggested to find the maximum power point (MPP) in photovoltaics. RDS uses the inherent ripple problem of the converter as a tool for finding MPP. By combining the proposed fast controller and the RDS algorithm, a fast and robust MPPT technique is obtained, which is simple to implement, eliminates the need for initial parameter tuning and is free from oscillations. Moreover, the proposed controlling method and MPPT algorithm are tested using Mitsubishi Electric MF170W module and their efficiency is compared with conventional methods (including P & O) in fast irradiation changing conditions. The proposed method harvests a 6% higher power than P & O and constant voltage. Compared with incremental conductance 24% more power is harvested. Finally, the practicality of the controller and algorithm was experimentally validated with a prototype system using a 5 W Evergreen module. |

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.
