ABSTRACT Uninterruptible power supplies (UPS) are used to provide power when regular utility power is unavailable.  Although they are commonly used for providing power in remote locations or emergencies, this is not because they are the same as auxiliary power units, emergency power units or standby generators. Unlike the aforementioned power... Continue Reading

ABSTRACT This project proposes a new type of voltage regulator based on single-phase converter otherwise known as transformerless AVR that compensates wide range voltage variations. This is not only capable of compensating variations at a much higher bandwidth but also does not experience mechanical wear down and is cost effective. The proposed... Continue Reading
