Inverters are mainly 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 necessary power voltage based on the motor's actual requirements to achieve energy-saving and speed regulation. Additionally, inverters feature numerous protective functions such as overcurrent, overvoltage, and overload protection. With the continuous increase in industrial automation, inverters have found extensive applications.
