What is a frequency inverter?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.
How does a DC inverter work?The inverter converts DC voltage into pure sinusoidal AC voltage with constant amplitude and stable frequency. The unit works with an IGBT inverter bridge with PWM (pulse width modulation) having high efficiency in the partial load range as well as achieving a low distortion factor at non-linear load.
How does inverter speed regulation work?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.
What are the components of a frequency inverter?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.
