摘要: In this paper, a universal direct current (DC) power supply system was developed and tested in order to provide uninterrupted for DC appliances. The employs simple Diode OR logic the three sources (mains from utility supply, solar photovoltaic battery). parallel combination of diodes at output functions like comparator circuit compares outputs voltage sources, so that highest particular time feeds supplies charging battery. under various operating conditions results obtained showed good performance system. outputs, when all were available, during failure only stored energy back-up battery available 13.8, 13.1 12.2V, respectively. guarantees an which can be used telecommunication equipment, audiovisual materials, computers, motor driven devices other A typical day radiation varied 547 W/m2 865 while generated PV 11.8 V 13.7 V. source increases with increase radiation.
