摘要：
This article proposes a dual-VSI DFIG-dc topology for high-voltage dc-grid applications. The dc-links of stator-VSI and rotor-VSI are connected in series to create high-voltage dc-link, eliminating or reducing the need of dc-dc converters. Further, the proposed topology is emulated as a voltage generation system in this article. An identical control technique for the stator-VSI and rotor-VSI is presented, which regulates the total series-connected dc-link voltage and supplies the required power at dc-link. This control technique incorporates the voltage balancing feature by employing two voltage equalizers (VEs) to maintain equal dc-link voltages of stator-VSI and rotor-VSI. The proposed control scheme has been verified for the proposed series-connected dual-VSI DFIG-dc topology with experimental results.
