Bantval Jayant Baliga (born {{{1}}}-{{{2}}}-{{{3}}}) is an Indian electrical engineer best known for his work in power semiconductor devices, and particularly the invention of the insulated gate bipolar transistor (IGBT).[1][2]

In 1993, Baliga was elected as a member into the National Academy of Engineering for contributions to power semiconductor devices leading to the advent of smart power technology, and in 2024, won the Finnish Millennium Technology Prize for his invention of the IGBT.[3][4]

Early life and education

Baliga grew up in Jalahalli, a small village near Bangalore, India. Jayant studied at Bishop Cotton Boys' School, Bangalore. He received his B.Tech in Electrical Engineering from the Indian Institute of Technology, Madras in 1969, and his MS (1971) and PhD (1974) in Electrical Engineering from the Rensselaer Polytechnic Institute.[1] Bantwal Vittal Manjunath Baliga, was one of India's first electrical engineers in the days before independence and founding President of the Indian branch of the Institute of Radio Engineers, which later became the IEEE in India. Baliga's father played pivotal roles in the founding of Indian television and electronics industries.[1][5] During his childhood his father inspired him a lot. Baliga remembers reading IEEE proceeding during his high school days which were brought home by his father. He graduated from high school in 1963.[6]

Career

He worked 15 years at the General Electric Research and Development Center in Schenectady, New York. In the early 1980s, he invented the insulated gate bipolar transistor that combines sciences from two streams: Electronics engineering and Electrical engineering. It is a transistor switch that was immediately put into production once invented.

This has resulted in cost savings of over $15 trillion for consumers, and is forming a basis for smart grid. This device is in use in many machines and devices using electricity, from kitchen appliances, medical devices, and electric cars to the electric power grid itself.

He joined North Carolina State University in 1988 as a Full Professor. He was promoted to Distinguished University Professor in 1997. He continues to innovate in electronics, even as an emeritus professor.[7]

He has founded three companies that made products based on semiconductor technologies.[5][8][9]

Recognition

  • In September 2024, it was announced that Baliga won the million Euro Millennium Technology Prize, supported by the Republic of Finland. The award ceremony is held on October 30, 2024 in Finland. He was honored for his invention in the 1980s of the Insulated Gate Bipolar Transistor (IGBT), which has dramatically increased the efficiency of devices using electricity, allowing precise digital switching of electricity. The device is used in wind and solar technology, in electric cars, in devices for maintaining or investigating human health, in kitchen appliances and more.[3][19]
