The voltage sag compensator, based on a transformer-coupled series-connected voltage-source inverter, is among the most cost-effective solution against voltage sags. When voltage sags happen, the transformers, which are often installed in front of critical loads for electrical isolation, are exposed to the disfigured voltages and a dc offset will occur in its flux linkage. In this paper, a new topology of series-connected compensator is presented to mitigate long duration deep sags, and the compensation ability is highly improved with a unique shunt converter structure acting as a parasitic boost circuit that has been theoretically analyzed using open loop & closed loop control schemes. Additionally, the proposed active voltage quality regulator is a cost effective solution for long duration sags that are lower than 50% of the nominal voltage as it is transformer less compared with the traditional dynamic voltage restorer.
