Description
In this project, a model-based design of a line-interactive Uninterruptible Power Supply (UPS) was developed. To mitigate power quality problems, the solution uses an active power filter based on a four-leg inverter and an energy storage system with electrostatic double-layer capacitors, known as supercapacitors, to withstand power grid voltage transients up to 3 seconds, in a 40kVA line-interactive UPS.
Subject Areas: Power quality; supercaps energy storage; four-leg inverter/active filter; line-interactive UPS
