| Abstract | In recent years, many electronic control systems and electrical driven units are introduced in vehicles and result in steadily increasing electrical loads. A new high-power, high-efficiency alternator system is needed to meet these requirements. Today's 14-V claw-pole synchronous generator is not able to meet the future power requirements due to its inherent design limitations. For this purpose, a claw-pole synchronous generator with pulse-width-modulation (PWM) rectifier regulated at 42-V is proposed in this paper. The ac voltage of the generator is controlled with excitation currents for achieving controllable condition of boost rectifier during varying speed. To improve the suppression of dynamic voltage during load-dump and jump-start charging, the dc output voltage of rectifier is regulated with stator current matching to load based on field-oriented control principle. A load current prediction feed-forward control approach is proposed in order to minimize the dc-link capacitance for compaction of the system. The proposed approaches are evaluated by the real-time simulation experimental results. |

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.
