Inverters are primarily composed of rectification (AC to DC), filtering, inversion (DC to AC), braking units, driving units, detection units, and microprocessor units. They adjust the output voltage and frequency by switching the internal IGBTs, providing the required power voltage based on the motor's actual needs 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.
