Interline hybrid unified power quality conditioner
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016This paper proposes a new interline hybrid unified power quality conditioner (IHUPQC) structure to improve the power quality of distribution feeders and to decrease the power ratings/voltages and switching losses of voltage source converters (VSCs). The IHUPQC consists of dynamic voltage restorer (DVR), an isolated dc-dc converter and a shunt hybrid ...

Unified Power Quality Conditioner
2002A unified power quality conditioner (UPQC) is a device that is similar in construction to a unified power flow conditioner (UPFC) [1]. The UPQC, like a UPFC, employs two voltage source inverters (VSIs) that are connected to a common dc energy storage capacitor.

A control strategy for unified power quality conditioner
2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004This paper presents a control strategy for a unified power quality conditioner. This control strategy is used in three-phase three-wire systems. The UPQC device combines a shunt-active filter together with a series-active filter in a back-to-back configuration, to simultaneously compensate the supply voltage and the load current.
