Design and implementation of a digital control and monitoring system for an AC/DC UPS

This paper presents the design and implementation of a digital control and monitoring module for an AC/DC uninterruptible power supply (UPS). A hardware and software of the system is developed. Moreover, a friendly graphical-user interface is provided. Management strategy of the UPS in different operation modes is described. The proposed digital control and monitoring system allows to realize the complex algorithms and this way increase the reliability and efficiency of the UPS.
