Abstract :
The paper deals with an optimized unified power quality conditioner (UPQC), which aims at the integration of series active and shunt active power filters with minimum VA loading of the UPQC. The series active filter is a dynamic voltage restorer (DVR), which regulates the voltage at the load end with minimum VA loading of the overall UPQC by voltage injection at optimum angle. The proposed scheme is validated by simulation and an experimental prototype in laboratory. Selected experimental results are reported along with analytical findings, which show the effectiveness of the proposed UPQC
