| Abstract | As far as the complexity of the current mode control is concerned, illogical choosing of the phase cross over frequency for a converter doesn't bring any significant advantages over the voltage mode control. So, one has to select the bandwidth carefully so that benefits of the current mode control will trade off with the complexity of implementing the scheme. The reported work emphasizes on the importance of choosing the optimum bandwidth in the current mode control which can claim all the benefits of this complex current mode control scheme. The advantages are: (a) reduction in the order of the controller due to decreased phase boost demand (b) scaling down in the size of the capacitor, inversely proportional to cross over frequency, of the compensator network and consequently demands very less current to drive as a network which prevents overloading of the output of the operational amplifier and, (c) improved response speed. In this paper, for demonstration purpose, the dynamic performance of the non inverting synchronous up down converter, second order converter, is carried out for both the voltage mode and the current mode feedback with different cross over frequencies. The simulation is carried out in Pspice. |

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.
