Voltage sag mitigation using a direct Matrix Converter

Conventional approaches for voltage sag mitigation relies on voltage source inverters (VSIs). The bulky DC link electrolytic capacitors used in VSIs are reported to be the reason behind majority of failures of these converters. Absence of these electrolytic capacitors in Matrix Converter(MC) makes it a more reliable and compact alternative than the VSIs. This paper reports the performance of MCs as a sag mitigating device for linear loads.
