Parameters estimation of a series VSC and shunt VSC to design a unified power quality conditioner (UPQC)

Abstract

Here, parameters is estimated of series and shunt voltage source converter (VSC) to design a three phase three wire UPQC for better understanding of VSC operation. The required parameters that could be considered while designing a UPQC are DC link voltage, capacitor value, shunt interfacing inductance, series interfacing inductance and series capacitance value. As the UPQC incorporates VSC thus, it is also required to design an appropriate switching frequency and ripple filter for both the VSC whereas a auxiliary device, series injection transformer is required to design for series VSC. The VA rating of series VSC is also needed while designing of the series voltage injection transformer. The performance analysis of a designed UPQC has been performed on MATLAB/Simulink.
