Abstract :
This paper deals with a new topology based on single-phase Z-source AC/AC converter for voltage swells or sags compensation. The proposed system is able to compensate voltage swells. In addition, it is also able to compensate up to over 50% voltage sag. A commutation strategy to drive the AC/AC converter is employed to realize snubberless operation. Analysis is presented; Simulation and experimental results at 20% voltage swell and 60% voltage sag are shown.
