The charger points booster circuit, step-down circuit and control circuit, four parts show circuit, control circuit by relay and the integrated operational amplifier LM358 complete circuit transformation. Mainly by using Mc34063 booster circuit chip, step-down voltage circuit mainly adopts the Mc34063 chip, control circuit used in road LM358 chip decided to relay voltage at both ends, and decided to relay the conversion switch, decided to buck circuit, boost work condition of the circuit. Show circuit AT89C52 SCM and modulus of conversion chip TLC549, able to measure the 0-5 V dc voltage value between, four digital display. Control circuit without plus auxiliary power from the power supply and can. So as to achieve in a continuous voltage transform can achieve sustained in charge. The charger charging high efficiency, and because the system set up by division element, cost is very low.【Key Words】 LM358; MC34063; AT89C52;TLC549; circuit transformation目录1绪论11.1 引言11.2选题简介、意义与背景21.3 系统功能指标22 系统结构设计52.1 主要设计内容52.2 设计思想52.3 系统结构73 系统升压电路、降压电路设计93.1 芯片简介93.2升压充电模块113.3降压充电模块123.4 升压电路123.4.1 升压电路工作原理123.4.2 以MC34063为核心的升压电路133.5 降压电路133.5.1 降压电路工作原理133.5.2 以MC34063为核心的升压电路144 系统单元电路设计154.1监测电路154.1.1模块功能介绍154.1.2监测电路工作原理184.1.3监测取样电路184.2控制电路194.2.1模块功能介绍194.2.2电路设计255 系统显示电路275.1 系统软件设计275.2系统板上硬件连线305.3程序设计内容316 总结分析326.1环境分析326.2设计总结32参考文献33总 结34致 谢36附录371 绪
