| Abstract | A novel feed-forward pulse width modulation (FF-PWM) technique is proposed for improving line regulation of buck or boost (BOB) converters. In order to provide a regulated supply voltage for portable devices, DC-DC converters should have a good line regulation whenever the voltage of the battery is higher or lower than the system supply voltage. Because of the consideration of cost and footprint area issues, we provide a novel BOB converter with FF-PWM, which can provide a regulated supply voltage without the use of transformers or voltage inversion. According to the value of input signals, BOB converters are also useful for dynamic voltage scaling systems or the radio frequency (RF) power amplifier (PA) because it can supply a dynamic voltage suitable for minimum power dissipation. Simulation results show the good line regulation of BOB converters due to the implementation of feed-forward pulse width modulation. |

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.
