An Insulated Gate Bipolar Transistor (IGBT) is a semiconductor device that combines the features of a bipolar junction transistor (BJT) and a field-effect transistor (FET). It is widely used in power electronics for switching and amplification applications. The IGBT is known for its high efficiency and fast switching capabilities, making it ideal for applications like inverters, motor drives, and power supplies. The IGBT operates by using a gate voltage to control the flow of current between its collector and emitter terminals. When a voltage is applied to the gate, it creates an electric field that allows current to flow, enabling efficient control of electrical power. This makes IGBTs essential components in modern electronic systems.
