Inverters are primarily composed of rectification (AC to DC), filtering, inversion (DC to AC), braking units, drive units, detection units, and micro-processing units. They adjust the output voltage and frequency by switching the internal IGBTs, providing the required power voltage based on the actual needs of the motor to achieve energy saving and speed regulation. Additionally, inverters offer numerous protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous increase in industrial automation, inverters have found extensive applications.
