high cost and complexity of control, interest in UPQC is growing due to its superior performance.
It can compensate signicant power quality issues, such as, voltage harmonics, voltage sag, voltage
swell, voltage unbalance, voltage icker, current harmonics, load reactive power, current unbalance,
and neutral current. A single-phase voltage-fed and current-fed UPQC are shown in Figures 38.33
and 38.34. Figures 38.35 and 38.36 show the schematic of a three-phase three-wire and a three-phase
four-wire UPQC.
