Frequency inverter relies on the internal IGBT to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving and speed regulation.
Frequency Control: The frequency of the output AC voltage is determined by the switching frequency of the IGBTs in the inverter stage. For instance, if an electric motor is designed to operate at a synchronous speed of , where is the speed, is the frequency of the power supply, and is the number of poles of the motor.
The basic design of a frequency inverter consists of just electronic components, without any mechanically moving components. Frequency inverters are made up of the following main assemblies: The rectifier converts the AC voltage on the input side into DC voltage.
Inverter speed regulation is achieved by changing the frequency of the power supply to the stator winding of the motor. First, the rectifier section converts the AC power supply to DC power. This usually involves a rectifier bridge, which converts the AC voltage to DC voltage.
In conclusion, frequency inverters are sophisticated yet essential devices that have revolutionized the way electrical equipment, especially motors, are controlled. Their ability to adjust frequency and voltage precisely has led to significant improvements in energy efficiency, performance, and flexibility in numerous applications.
A frequency inverter’s primary function is to manage motor performance by adjusting the electrical supply, but the way it does this can vary depending on the method of control used and the motor's specific demands. Here's a breakdown of how frequency inverters influence motor performance:
