This document describes a proposed design for a Unified Power Quality Conditioner (UPQC) that uses fuzzy logic control to minimize DC link voltage fluctuations and improve power quality. The UPQC combines series and shunt inverters to compensate for voltage sags/swells, unbalanced voltages, harmonics, and reactive power. Fuzzy logic controllers are used to stabilize the DC link voltage and balance active power between the inverters. Simulation results show the fuzzy logic control provides better DC link voltage regulation compared to PI control, improving the UPQC's ability to compensate for power quality issues.
