In energy transmission systems, effective equipments on power control are generally known as Flexible AC Transmission System (FACTS). In addition, the power electronics-based equipment, which are called power conditioners are use to solve power quality problems. Since the topologies of these equipments are similar to those used in FACTS equipment, power conditioners are also called Distribution FACTS...
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...
This paper proposes a new type of voltage swell/sag compensator based on single-phase Z-source AC/AC converter. The proposed topology employs a pulse width modulation (PWM) Z-source AC/AC converter along with a transformer. A commutation strategy to drive the AC/AC converter is employed to realize snubberless operation. Circuit analysis is provided. Simulation and experimental results at 20% voltage...
