Abstract: In order to solve the problems of fire alarming device continued power supply,the simulation control technology was investigated. The shortage of 5 V/2 A DC uninterruptible power system was pointed,and a method to simple circuit design was proposed. The principle of circuit was analyzed,and the function of pulse charging for battery,short-circuit protection and over-current protection was increased. The principle of waveform was given and analyzed after test. The experimental results show that the design is simple and practical. Each function is implemented and it meets the design requirements.
Key words: simulation control;uninterruptible power system;fault testing;cell pulse charging
