As the United States transitions to cleaner energy and more U.S. consumers adopt electric vehicles, the grid is facing new power flow demands. ORNL researchers are tackling this challenge by creating a new architecture to modernize the grid from the bottom up, starting with consumers and expanding to the entire power distribution system. A cornerstone of this architecture is a new power electronics technology suite called a Smart Universal Power Electronics Regulator, or SUPER.
The approach combines hardware and software to monitor equipment health, speed up communication and increase security. In the long run, that means fewer and shorter blackouts for customers, savings for utilities and a more reliable grid.
The intelligent power stage, or IPS, can be removed or replaced without shutting down the system, Krishna Moorthy said. Compared with existing technology, an IPS has more sensors and computational ability, enabling it to monitor its components and detect problems sooner.
The Murthy Govindaraju Research Endowment Award has been instituted in 2021 in the Division of Electrical, Electronics, and Computer Sciences (EECS) by alumnus Dr. Madhukar Govindaraju and his wife Dr. Chaya Murthy in memory of alumnus the Late Mr. M. S. Srinivasa Murthy through an endowment to IISc.
The Murthy Govindaraju Research Endowment Award is open to all Undergraduate, Integrated PhD and PhD students, as well as, Research Project Assistants and Postdoctoral Fellows of the Division of Electrical, Electronics and Computer Science at IISc for their excellence in academic research, to materially advance the efficiency, size and performance of Power Electronics and applies them to benefit a wide range of real world applications and encompass improvements in the generation, conversion, control and application of electrical energy, including exploring new system architectures, circuit designs, and control methods that together enable substantial increases in operating frequency over the present state of the art. The research should also apply them in a variety of applications. Automotive power generation and control is one such area where the application of power electronics to enhance the efficiency, power, and transient performance of automotive alternators is critical for Electric Vehicles (Cars, Trucks, Trains, etc.), with the goal of enabling improved performance, safety, and comfort in vehicles. Other areas of Research could include power components and circuits for industrial, commercial, consumer, and medical applications where improved size, efficiency, and performance are of critical importance.
The Murthy Govindaraju Research Endowment Award has been jointly set up by Madhukar C. Govindaraju (1990 Graduate of the Master of Engineering Program from the Department of Computer Science and Automation, IISc.), and his wife, Chaya Murthy Govindaraju, to honour the Late Mr. M. S. Srinivasa Murthy, who was a IISc graduate in 1956 from the Department of Electrical Engineering.
Mr. M. S. S. Murthy graduated with a Diploma of the IISc. (D.I.I.Sc) In Electrical Technology in 1956 and started his career at Kirloskar Electric in the Transformer Engineering Division. Later from 1964 to 1987, he held several key positions at Bharat Heavy Electricals Ltd. (BHEL), including the Head of the Power Electronics Division (PED), Executive Director for the Control Equipment Division (CED), the Industrial Systems Group (ISG), and the Electro Porcelain Division (EPD). At BHEL, he was engaged in several key projects in the design, engineering, construction, testing, commissioning, and servicing of a wide range of products and services. Later from 1987 and until his retirement in 1996, Mr. M. S. S. Murthy held several Executive roles as the Technical Director of the English Electric Co. of India, Technical Director of India Meters Ltd., and the Chief of Technology at GEC Alsthom, responsible for technology innovation, investments, and Information Technology infrastructure projects during his long and successful tenure. Throughout his career, Mr. M. S. S. Murthy was a role model and mentor to the younger generation of engineers and scientists by not just modelling great ethical behaviour in the industry but also helping them find their passion to innovate. Mr. M. S. S. Murthy has been a Senior Member of the IEEE, a Lifetime Fellow of the Institute of Standards, India, a Lifetime Member of the National Institution for Quality and Reliability (NIQR) and a member of the American Society for Quality (ASQ).

The Journal of Applied Research and Technology (JART) is a bimonthly open access journal that publishes papers on innovative applications, development of new technologies and efficient solutions in engineering, computing and scientific research. JART publishes manuscripts describing original research, with significant results based on experimental, theoretical and numerical work. The journal does not charge for submission, processing, publication of manuscripts or for color reproduction of photographs. JART classifies research into the following main fields: Material Science Biomaterials, carbon, ceramics, composite, metals, polymers, thin films, functional materials and semiconductors. Computer Science Computer graphics and visualization, programming, human-computer interaction, neural networks, image processing and software engineering. Industrial Engineering Operations research, systems engineering, management science, complex systems and cybernetics applications and information technologies Electronic Engineering Solid-state physics, radio engineering, telecommunications, control systems, signal processing, power electronics, electronic devices and circuits and automation.
