Bantval Jayant Baliga (born in Chennai) is an Indian

electrical engineer Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the l ...

best known for his work in power semiconductor devices, and particularly the invention of the insulated gate bipolar transistor (IGBT). Dr. B. Jayant Baliga wrote: "Power semiconductor devices are recognized as a key component of all power electronic systems. It is estimated that at least 50 percent of the electricity used in the world is controlled by power devices. With the wide spread use of electronics in the consumer, industrial, medical, and transportation sectors, power devices have a major impact on the economy because they determine the cost and efficiency of systems. After the initial replacement of vacuum tubes by solid state devices in the 1950s, semiconductor power devices have taken a dominant role with silicon serving as the base material. These developments have been referred to as the Second Electronic Revolution". 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.

Career

Baliga grew up in Jalahalli, a small village near Bangalore, India. His father, 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. Jayant 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
