Which of the following statements correctly describe the need for a back-to-back converter connected to the rotor of a doubly fed induction generator [DFIG] used in wind power plants? (i) It feeds the rotor with currents of fixed frequency and thus helps in achieving a fixed range of speed. (ii) It feeds the rotor with currents of varying frequency and thus helps in achieving various ranges of speed. (iii) It helps in power factor correction by adjusting the active power output of the DFIG. (iv) It helps in power factor correction by adjusting the reactive power output of the DFIG.
