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.
