The article discusses the groundbreaking invention of the Insulated-Gate Bipolar Transistor (IGBT) by Jayant Baliga, a professor at North Carolina State University. The IGBT, a hybrid between a transistor and a thyristor, revolutionized the field of power electronics by enabling more efficient and compact power conversion systems. This innovation has had a profound impact on various industries, including electric vehicles, renewable energy systems, and industrial motor drives. Baliga’s work has been recognized with the prestigious Millennium Technology Prize, often referred to as the “Nobel Prize for technology,” which carries a cash award of 1 million euros. The article highlights the significance of the IGBT in enabling energy-efficient technologies and its role in addressing global challenges such as climate change and sustainable energy production.
