摘要

This paper presents an analysis of current source inverter (CSI)-based unified power quality conditioner (UPQC) to improve the electric power quality at distribution levels. In recent years unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both voltage as well as current harmonics in a polluted power system network. Fabrication of UPQC is done implying both current source and voltage source inverter. Current source UPQC has unique advantages over generalised voltage source-based UPQC. Reference and switching signals are derived using a simple PI controller and robust hysteresis band PWM technique respectively. The resultant compensation system eliminates voltage as well as current harmonics with good dynamic response. Extensive simulation results using MATLAB/Simulink and SimPowerSystems software for R-L load connected through an uncontrolled bridge rectifier is presented for performance evaluation.
