Effect of Power Losses on the Operation of Matrix Converter Based Dynamic Voltage Restorer

Voltage disturbances especially voltage sags can cause significant problems and losses for electricity users. Dynamic voltage restorer (DVR) is a series compensator device that can protect sensitive loads from grid side disturbances. To do so, in this paper a DVR based-on 3phase-to-3phase matrix converter (MC) topology is proposed. In the modeling of MC the switching and conduction losses of the converter are taken into account using a novel precise technique. The effects of the MC losses on the operation of the DVR are analyzed using the PSCAD/EMTDC software.
