A Control Method For Two Types Of Three-Phase Transformerless Unified Power Quality Conditioner
2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA)（2018）
Abstract
This paper compares two types of three-phase transformerless unified power quality conditioner (UPQC) and analyzes their performance under different grid or load conditions. Unbalanced grid voltage or load current will cause the DC-side voltage imbalance with the traditional control strategy. Thus an improved control method is proposed to suppress the DC-side voltage imbalance, which is analyzed in detail. Finally, the correctness of the proposed method is verified by PLECS simulation.
