Abstract: The conventional Unified Power Flow Controller (UPFC) exists two back 2 back inverters and more complex zigzag transformers for isolation and accomplishment high power & voltage ratings. To overcome these difficulties, two zigzag transformers are wholly eliminated in this place two cascaded multi-level inverters are presented. The single configuration and control of two CMIs as a power flow controller lead to the possible to separately control real and reactive power over a transmission line. The proposed configuration is exceptional features and several advantages over the traditional UPFC such as transformer less, high efficiency, light weight, low cost, high reliability and fast dynamic response. In this work, Fuzzy Logic Controller (FLC) is design to improve the system performance. In this work is done by MATLAB Simulation model.
