Fig. 4. Typical back-to-back arrangement of inverter and converter circuits to control power flow. At the current state of development, most DFIG power electronics utilise a two-level six-switch converter, Fig. 4. Two-level refer. . The rotor-side converter (RSC) applies the voltage to the rotor windings of the doubly-fed induction generator. The purpose of the rotor-side converter is to control the rotor currents such that the rotor flux position is optimally oriente. . The grid-side converter aims to regulate the voltage of the dc bus capacitor. Moreover, it is allowed to generate or absorb reactive power for voltage support requirements. The function is realized with two control loops as well: an. The DFIG is an induction machine with a wound rotor where the rotor and stator are both connected to electrical sources, hence the term ‘doubly-fed’. [pdf]
