چکیده
Single phase unified power quality conditioner (UPQC) consists of series and shunt active power filter (APF) with common dccapacitor. Series converter acts as voltage source converter and shunt converter acts as current source converter. Use of non-linear loads results in voltage and current harmonics. These harmonics can be eliminated by using single phase UPQC. So that, which also improves the power quality at the point of common coupling (PCC). This paper presents control methods of single –phase d-q theory and fourier analysis of single-phase UPQC. The two control methods are studied, analyzed and simulation models are developed for two methods using MATLAB software. The simulated results show that for distorted supply power quality is improved and the total harmonic distortion of source current are compared for two control methods.
