| Abstract: | In order to solve the problem that the communication and monitoring equipments don't work due to grid failure,a mine-used uninterruptible power supply was designed. The management of uninterruptible power supply was realized by DC-DC Converter XL2576,LM317 T and LM339. When AC power is not normal,the Ni-MH battery supplies power,so the continuous work of the loaded resistance is ensured. The test results showed that the designed power supply has low load effect and source effect lower than 5%,wave voltage under 1%,the specification reached the requirements of intrinsically safe electrical equipment. |
