Abstract

This paper presents a three-phase to singlephase six-leg converter for a wind energy conversion system based on Doubly-Fed Induction Generator (DFIG). The converter is composed of six legs and is divided in three parts: the grid-side converter (GSC), which is responsible for power factor and DC-link voltage controls, the stator-side converter (SSC), which guarantees the control of the stator voltage, and the rotor-side converter (RSC), which is responsible for vector control of the generator. One of the converter’s legs is shared by gridside and stator-side converters. The main advantages of the proposed configuration compared to other topologies presented in the literature are providing balanced threephase voltages to the DFIG, simple control system and not having any limitation with respect to synchronization between grid and stator voltages and DC-link voltage. The system model, pulse-width modulation (PWM) and control strategies are discussed and simulation and experimental results are presented in order to prove the feasibility of the system.
