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.

    Analysis and harmonic reduction in different multi-pulse converter topologies
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-02) Chauhan, Gokul Singh; Singh, Sunil
    Power electronics devises which are used by the power industry in the past two decades are increased. Which are the main source of harmonic in now a day. In this the simulate -pulse converters are developed in MATLAB/SIMULINK for improving power quality by reducing harmonics in ac main. We have also improved the power factor of input and ripple factor of dc output and analyzed the effect of source inductance on THD, ripple factor and input power factor. The simulation of 12-pulses, 18-pulses and 24-pulses multi-pulse is performed on MATLAB/SIMULINK for R, RL, RC and D.C. motor as load. The THD, ripple factor and input power factor are calculated for 12,18 and 24 multi pulse converters. The primary winding of the transformers is connected in zigzag, while the secondary windings of the transformer are connected to the converter. By choosing appropriate phase shift between the primary and secondary sides of the transformer the lower order harmonica can be eliminated in pair. so, a very high power quality voltage and current waveform can be synthesized. Comparison of THD (total harmonic distortion) in the input current, ripple in the output voltage and power factor of input side is done in this work. Now we can conclude that performance of uncontrolled converters is better than controlled converters. THD and ripple factor is improved as we go from lower pulse to higher pulse. 24-pulse is more economical and gives better results then 18-pulse converter.
