| Abstract | Electric vehicle (EV) battery chargers operate from moderate switching frequency (MSF) to high switching frequency (HSF) to achieve high power density. To operate the HSF power electronic devices, the selection of gate drivers and its associated components is crucial. Laboratory developed gate driver circuits (GDCs) often fail to drive these HSF devices adequately due to noise vulnerability, PWM duty loss and common-mode currents. Further, at MSF and HSF ranges, the gate-to-source terminals of the device are subjected to high voltages due to unwanted noise resulting in false turn-on of the switch leading to the converter failure. In this paper, firstly, an improved GDC and it's associated component selection criteria are proposed for HSF EV application. The proposed GDC is simple in structure with minor components; thus, it is cost-effective and highly reliable. Secondly, the proposed GDC is compared with the other commercially available competent GDCs. Power losses, cost and dynamic switching performance are the figures-of-merit for the quantitative assessment. From the comparison, it will be shown that the proposed GDC exhibits an overall superior performance among the popular GDCs. Finally, the distinctive features of the proposed GDC are experimentally validated for several test cases and the obtained results are presented. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
