In Power Electronics, the insulated-gate bipolar transistor (IGBT) is one of the most widely utilized semiconductors. Modern IGBTs are built of Silicon Carbide (SiC) and Gallium Nitride (GaN) for better production and thermal efficiency.

While IGBTs are helpful for power supply and conversion, they may also create a lot of heat when switched at high frequencies.


The cooling of IGBT devices is a significant concern for electric power engineers.

Development of IGBTs
The IGBT is a stronger switch that operates by controlling the voltage to a semiconductor part to generate an electrical circuit. It was first introduced in the 1980s, and it was enhanced on the metal oxide semiconductor field-effect transistor's invention (MOSFET).

 

The IGBT is unusual because it eliminates the thyristor function, resulting in a more efficient device. Inverters, motor drives, and power systems for advanced solar and wind turbines are all made with IGBTs.

 

Thermal Management of IGBTs
Electric power production, conversion, transmission, and distribution require the use of power electronics equipment. Power technologies are being deployed to increase energy efficiency, dependability, and control. Some experts believe that all electrical power will travel through a power semiconductor device at some point in the future.

 

IGBTs are high-voltage, high-power gadgets that are becoming increasingly popular. An IGBT (insulated-gate bipolar transistor) is a solid-state switch that enables electricity to flow when it is turned on and shut down.

 

An IGBT works by delivering a voltage to a semiconductor component, changing its properties and allowing it to block or produce an electrical path.

 

For moderate frequency (5-50 kHz) and high voltage (200-2,000 V) applications, an IGBT combines an insulated gate input with a bipolar output to produce a dependable power switch.

 

Large IGBT modules often include multiple devices connected in parallel and can handle hundreds of amperes of current with blocking voltages as high as 6,500 V. Hundreds of kilowatts of power may be controlled by these IGBTs.

 

IGBTs are used in a wide range of high-power applications, including electric and hybrid vehicles, battery chargers, electric buses, appliance motor drives, switch and power supplies, voltage control converters, motor drive controls, solar and wind power inverters, thermal management, and medical diagnostic devices.
