ICMACC Tutorial | Power Electronics at its Best in High Voltage, High Power Applications on 6th November 26

We are delighted to invite you to the 3rd International Conference on Recent Trends in Microelectronics, Automation, Computing, and Communication Systems (ICMACC-26), being organized by Circuits and Computing Branches, VNR Vignana Jyothi Institute of Engineering and Technology (VNR VJIET) in association with the IEEE Hyderabad Section, from 5-7 November 2026. A Tutorial on Power Electronics at its Best in High Voltage, High Power Applications Abstract Electric power sources are frequently located away from population centers. Therefore, the electricity must be transported from the power sources to consumers through transmission and distribution lines. The voltage changes its magnitude and phase angle at any point along a line due to the voltage drop across the line impedance, which is caused by the flow of current in the line. However, the voltage at a point-of-common-coupling with a load must be maintained within the regulatory limits. Voltage regulation techniques have been practiced in power grid applications with the use of inductors, capacitors, transformers and load tap changers (LTCs) since the earlier days of electrical engineering. However, the latest trend is to use more and more power electronics-based solutions. Even though the costs of the available solutions vary widely, the basic underlying theory of voltage regulation is still the same as it has always been. The voltage control techniques are applicable in electric transmission lines as well as various other applications, such as motor drives, flicker control, harmonic mitigation, data center loads, and so on. In examining the various solutions for voltage regulation, the presenter discusses how these solutions address both functional needs and cost demands. Speaker: Dr. Kalyan K.
