N2 - This paper presents the application of a single-phase parallel converter as an uninterruptible power supply and demand side management system. The proposed system consists of a bi-directional inverter that is connected in parallel to the utility system. When the grid system fails, the converter will convert the power from the battery to the ac side (utility side) at the mains voltage and frequency. On the other hand, when the utility is normal the converter will act as a demand side management system. It charges the battery during low load and shaves the transient load at the peak period system. This improves the pattern of the demand variation in the utility side. This paper presents the operational principle of the Uninterruptible Power Supply and Demand Side Management System, laboratory, and simulation results.
