Explanation
An IGBT (Insulated Gate Bipolar Transistor) is a power electronic component that is widely used in power electronics. It is a hybrid transistor that combines the advantages of bipolar transistors (BJTs) and field effect transistors (FETs).
An IGBT consists of an N-channel MOSFET structure controlled by a P-channel bipolar transistor. It combines the high input impedance of a FET with the high current gain of a BJT. The IGBT can therefore be used as a switch or amplifier in high power applications where high currents and voltages need to be switched or controlled.
The main application of IGBTs is in power electronics, such as in inverters, switched-mode power supplies, frequency converters, motor controls, welding equipment and applications in the field of renewable energies such as wind turbines or solar inverters. With their ability to handle high switching frequencies and high currents, IGBTs are an essential part of modern power electronics, enabling efficient and precise control of electrical power in a variety of industrial applications.
