Abstract The relationship between overvoltage ratio, power factor, phase shift angle and compensation voltage is analyzed. Then the investigation into the DC-link voltage pumping-up from the viewpoint of real power flow is conducted and a novel closed-loop phase shift control method based on the DC-link voltage is proposed. The experiment achieved in the laboratory examined the feasibility of the proposed idea. The result shows that the active voltage quality regulator (AVQR) based on the proposed idea performs very well in sustaining DC-link voltage, and it also ensures the progressive phase shift of load voltage. Two AVQR with respective rating of 50kVA and 100kVA are also developed afterwards. They are been successfully integrated into a realistic power system environment and have a good performance of mitigating voltage disturbances.

Key words： Phase shift progressive phase shift AVQR DC-link voltage pumping-up DC-link voltage control
