For variable speed wind turbines, one of two types of generators can be used: a (doubly fed ) or an FRC (fully rated converter). A DFIG generator draws from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure. A DFIG configuration will require the generator to be a wound rotor; squirrel cage rotors cannot be used for such a configuration.

V/F Control, or Volts per Hertz control, is a simpler and more traditional method used in frequency inverters. Two primary control methods used in these devices are Vector Control and V/F Control. This method ensures that the voltage and frequency remain proportional, maintaining a constant magnetic flux within the motor. By doing so, the v/f model prevents issues like magnetic saturation and. . The most popular algorithm for the control of a three-phase induction motor is the V/f control approach using a natural pulse-width modulation (PWM) technique to drive a voltage-source inverter (VSI), as shown on Figure 1-1. Volts-per hertz, commonly called V/f, can be deemed as the simplest motor control method. . A frequency inverter, also known as a variable frequency drive (VFD), is an essential device used to control the speed and torque of electric motors by adjusting the input frequency and voltage.
