Frequency inverters are electronic devices that create an AC voltage with variable frequency from an AC voltage with fixed frequency (e.g. 50 Hz). They are usually installed between the supply network and an electric motor so that its speed can be controlled steplessly and precisely and so that its energy consumption can be optimised.
Frequency inverters are made up of the following main assemblies: The rectifier converts the AC voltage on the input side into DC voltage. The electrical components needed for this are known as uncontrolled or controlled bridges, such as thyristors or transistors.
While most motors are designed to operate at a frequency of 50Hz, there are many situations where higher speeds are necessary. Frequency inverters provide the flexibility to run motors above 50Hz, allowing for increased operational speeds and improved performance in certain applications.
1. What is the frequency of AC inverter? An AC inverter frequency refers to the number of power signal fluctuations, typically measured in Hertz (Hz). In most regions, the standard inverter frequency for AC power systems is 50 or 60 Hz, representing the number of complete cycles per second.
