In the context of motor drives, IGBTs are employed in Voltage Source Inverters (VSIs) to convert a fixed DC voltage into an AC voltage with variable frequency and amplitude. This AC voltage is then utilized to govern the speed and torque of the motor. The inverter is build of switching devices, thus the way in which the switching takes place in the inverter gives the required output. The inverter is primarily used for power conversion for two purposes: Power-to-power: Electricity conversion for transmission, distribution or energy storage. An example is a solar inverter, inverting the direct current coming from the. . The inverter device's role is to control the voltage and frequency of the power supply and seamlessly change the rotation speed of motors used in home appliances and industrial machineries.

Switching Frequency: IGBTs allow for relatively high switching frequencies (typically 5 kHz to 30 kHz in solar applications). Higher frequencies enable smaller passive components (inductors, capacitors), leading to more compact and potentially lower-cost inverter designs. . Proliferation of high-performance power conversion equipment in applications such as solar inverters, UPS, motor drives, inductive heating, welding, automotive and traction has rekindled the interest in understanding and optimizing IGBT characteristics in order to optimize the system performances. Selecting the right IGBT for an inverter application requires careful consideration of voltage. . For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) ofer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT. Since, thermal design is an important consideration in any power electronic converter, an optimized design is necessary for efficient. .
