An IGBT (Insulated Gate Bipolar Transistor) is a power semiconductor device commonly used in high-efficiency and fast-switching applications. It combines the easy gate control of a MOSFET with the high-current and low-saturation-voltage capability of a bipolar transistor. IGBTs are widely used in motor drives, inverters, electric vehicles, UPS systems, and induction heating due to their ability to handle high voltage and current with minimal losses. They offer efficient switching performance and are essential in modern power electronics for controlling large amounts of power with precision.
