摘要
介绍了一个具有电池后备的微机测控系统的电源设计 .此电源由AC/DC和DC/DC变换器产生系统所需的各种电压 ,由UC3 90 6等元件组成“双电平浮充充电器” ,由继电器完成主电 /备电之间的切换 ,由检测电路判断电源部分的工作状态 .本设计达到对电源部分的技术要求 .
This paper discusses the design of power supply with reserve battery of the microcomputer measure control system. In this design, a AC/DC converter and a DC/DC converter are used to generate all the voltages needed by the system; the dual level float charger consists of UC3906 and several other components; a relay switches on/off main power supply and secondary power supply; a checking circuit determines the work states of the power unit . The design meets the specifications of the power unit.
