| Abstract | For the unmanned military robotic platforms and exploration vehicles, the frequent external charging of energy storage devices (batteries) are not feasible. In such cases photovoltaic are preferred as backup for the energy storage devices, which charge these devices onboard. But the low energy conversion efficiency of photovoltaic is much of a concern. Hence every attempt of extracting the maximum output from photovoltaic (PV) is greatly appreciated, especially in military platforms where size and weight of the PV array is constrained. Furthermore the mobility of these platforms adds to the inefficiencies of the array by partial shading and dynamic irradiance. Few methodologies proposed for maximizing the output and increase efficiency includes Maximum Power Point Tracking using Adaptive Resonance Theory (ART2) Artificial Neural Network algorithm and unsupervised learning using improved incremental conductance algorithm, which tracks the maximum power point of the photovoltaic array that fluctuates along with the fluctuations in irradiance of the sun using an efficient neural network. Also determining the angle of sun with the MEMS digital sun sensors and aligning the modules accordingly, increases the input irradiance received by the panel. The techniques for bypassing other sources for inefficiencies like shading effect, thermal effect is also presented. The integration of various modular systems together ensures the effective utilization of the available solar energy hence increasing the efficiency. The simulation confirms the facts and illustrates the increase in output efficiency of the PV module for onboard backup charging of the energy storage device on a military mobile platform. |

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.
