Implementation and evaluation of a new dvr topology with ac link for series compensation
This paper introduces a new three-phase dynamic voltage restorer (DVR) working in series compensation with an AC link, called AT-DVR. One of the main features of AT-DVR is an AC/AC buck converter, which is used to obtain the AC voltage for compensation. AT-DVR has the capacity to mitigate sag and sw...

| Summary: | This paper introduces a new three-phase dynamic voltage restorer (DVR) working in series compensation with an AC link, called AT-DVR. One of the main features of AT-DVR is an AC/AC buck converter, which is used to obtain the AC voltage for compensation. AT-DVR has the capacity to mitigate sag and swell events. A dynamic model of AT-DVR is presented in order to explain its advantages and its limitations. PI and fuzzy controllers were implemented to guarantee mitigation of sag and swell events, and these were evaluated using four performance indexes via simulation. Finally, a hardware implementation of the AT-DVR is described, and its behaviour when a fault occurs is demonstrated |
