Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Modelling and simulation of matrix converter using space vector modulation techniques
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Misra, Sudheeksha; Arora, Sudha
    In today’s world there is a demand for intelligent power supply systems for different industrial applications and for fulfilment of all these modernization needs the industries require a different types of intelligent power converter for their process and hence, AC to AC power converter are becoming essential for the industrial applications. This conversion is usually done using the traditional converter consisting of rectifier and inverter linked by a storage element normally the electrolytic capacitor which makes the converter bulky and reduces the reliability of the system. Hence, to overcome this drawback, Matrix Converters are gaining the researchers attention as an alternative to the traditional converters. The Matrix converter is the most versatile converter and has many advantages over the other converters such as it directly convert AC to AC without any dc link, has compact design, bi-directional power flow capability, generate high quality desired waveform. In this thesis the fundamental of Matrix Converter, its switching conditions and the different bi-directional switches which are used in Matrix Converter are discussed. The Matrix Converter has many modulation techniques invented up till now but the most efficient is the Space Vector Modulation technique, In the terms of the Matrix Converter, the Space Vector Modulation technique is of two types Direct Space Vector Modulation and Indirect Space Vector Modulation and both the Direct and Indirect space vector modulation have been discussed in detail in this work with its implementation using the MATLAB/Simulink environment and from the results and analysis it has been concluded that the Indirect Matrix Converter has higher THD for input and output currents as compare to the Direct Matrix Converter.
