Abstract: Unified Power Flow Controller (UPFC) is one of the most important device in FACTS family, this device in this work is used for power quality improvement. In this paper three level inverter is proposed for UPFC for the reduction of harmonics and for the enhancement of power transfer capability. SVPWM technique decides switching pattern of three level inverter. Therefore, in this paper this method is applied for controlling the three level inverter output. The proposed method is applied on four bus system and results are compared with UPFC without three level inverter. Results demonstrated that the proposed method effectively decreasing the harmonics and increasing the power transfer capability. 
Keywords: Multilevel Inverter (MLI); Unified Power Flow Controller(UPFC); Space Vector Pulse Width Modulation (SVPWM).
