Line-Interactive UPS as Shunt Active Power Filter
2019 International Conference on Electrical Drives & Power Electronics (EDPE), 2019 This paper describes a newly proposed solution for using the line-interactive uninterruptible power supply (UPS) system as a shunt active power filter. An overview of active power filters topologies and control strategies for active power filters are presented. The proposed solution is compared to similar solutions.

Power Quality Improvement using Shunt Active Power Filter
, 2020 Nowadays, usage of non linear loads in power system is increasing. For example, UPS, inverters, converters, etc. These loads make the supply current non sinusoidal and distorted form, which is called harmonics. At this time Active power filters have been developed to improve power quality.
