Abstract

This paper describes the development of a high-performance single-phase line-interactive Dynamic voltage Restorer, which is composed of a full-bridge inverter and super- capacitors. The operational feasibility was verified through computer simulations with PSCAD/EMTDC software, and experimental works with 3 kVA prototype. The developed system can compensate the input voltage sag and interruption within 2 ms, in which the maximum allowable duration of voltage interruption is 2 seconds. It can be effectively used to compensate the voltage interruption in the sensitive load, such as computer, communication equipment, automation equipment, and medical equipment.
