Abstract :Faults in transmission and distribution networks often cause voltage sags. Direct matrix converter insert ignore into journalissuearticles values(DMC);-based drives are a new generation of electrical drives. Unlike the conventional two-stage diode supply-side inverter drive, the DMC drive has no direct current insert ignore into journalissuearticles values(DC); link capacitor and no capacitor charging-time delay before operation. The absence of a DC link makes the DMC-based drive more sensitive to voltage sags. The above-mentioned faults in transmission and distribution networks could degrade the DMC drive`s performance and reliability. This paper investigates possible kinds and levels of voltage sags, dependency on network configuration, and the behavior of the DMC-based drive under abnormal input line-voltage conditions. Modification of the DMC drive control to reduce the influence of voltage sags is proposed and verified.
