- Unified power quality conditioner (UPQC) is one of the most comprehensive FACTS devices which can controls three system parameters independently. In this system a novel configuration of UPQC which consists of a twelve switch converter parallel with a series. Capacitor has been proposed to inject desired series voltage. It means that operation of twelve-switch converter in this configuration be the same as combination of two converters in conventional UPQC. However, proposed configuration requirements less power electronics switches and gate drive circuits and control scheme becomes simpler than conventional UPQC configuration, using series capacitor parallel by twelve switch converter reduce the injection voltage"s THD, eliminate output filter, also decrease the converters power rating in comparison with conventional UPQC composed of series and shunt converters. The proposed UPQC is modeled using MATLAB/SIMULINK software and simulation results are presented to indicate good operation of the new UPQC
