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