摘要: 设计了一种煤矿井下交换机用直流不间断电源。该不间断电源采用MAX713电源管理芯片对镍镉电池进行智能充电；采用MSP430F147单片机作为微处理器，利用外部中断方式监测矿用交流电的工作状态，当发现矿用交流电不能正常供电时对电路进行切换，启动镍镉电池供电，从而保证交换机持续工作。测试结果表明，该不间断电源具有一定的实用性。

Abstract: A DC UPS used in underground exchanger was designed. The UPS uses MAX713 to make intelligent charging for Ni-Cd battery; it takes MSP430F147 as microprocessor, uses external interruption mode to monitor working state of mine-used AC, and it can switchover to start Ni-Cd battery supply when mine-used AC has fault, so as to ensure continuous work of exchanger. The test result showed that the UPS has certain practicality.
