The research and design of the intelligence UPS power supply
Abstract: On-line UPS, with the function of stabilizing the voltage and the frequency , filtering and resisting the interaction , has been extensively used in every field of the national production, especially for the computer system. In this paper, design a on-line UPS based on 8031 CPU for computer technique was developed. The working principle and the design of hardware and software of the UPS was introduced. The full-digital/intelligent control of the UPS was realized by means of advanced electric/electronic technology and computer control technique. First introduces the definition of UPS. It is along with the development of Information and popularity of computer , equipment with high technology put forward more and more strict demand for quality of power supply. But at times, power a from wall socket is neither clean nor uninterruptible. Many abnormalities such as blackout, brownout, spikes, surges, and noise can occur. This is the function of an uninterruptible power supply(UPS) to act as a buffer and provide clean, reliable power to uninerable electronic equipment. The design Introduced the development classify and present conditions of UPS systematically.
Key words: power supply; UPS(Uninterruptible power supply); on line; 8031 microcontroller.
