What is the basic frequency of an inverter?
The frequency corresponding to the maximum output voltage of the inverter is called the basic frequency; b. When the output voltage of the frequency converter is equal to the rated voltage, the minimum output frequency is called the basic frequency. The fundamental frequency is represented by fBA.
How does a frequency inverter work?
In Central Europe, the grid frequency is 50 Hz. Frequency inverters first convert the incoming AC voltage into DC voltage and then back into (adjusted) AC voltage. As a result, the downstream motor has a steplessly adjustable speed range between 0 and the rated speed, without losses in torque.
What is the difference between voltage-driven and current-driven frequency inverters?
Current-driven frequency inverters keep the ratio of current to frequency constant; voltage-driven models stabilise the ratio of voltage to frequency. In Central Europe, the grid frequency is 50 Hz. Frequency inverters first convert the incoming AC voltage into DC voltage and then back into (adjusted) AC voltage.
