Power quality problems have been increasing due to the wide use of nonlinear loads. Nonlinear loads cause harmonic currents in networks and consequently distort the voltage and current waveforms at the point of common coupling. Unified Power Quality Conditioner (UPQC) is an efficient custom power device for enhancing the electric power quality at distribution levels. The UPQC is a combination of series and shunt active power filters sharing a common dc-link capacitor. This proposed system consists of a unified power quality conditioner integrated with a 7-level flying capacitor multilevel...
