  • 单片机控制的铅酸蓄电池充电电源

     为了有效地提升铅酸蓄电池的使用寿命,同时实现对充电过程的监控,设计出一种用单片机控制的36 V铅酸蓄电池充电电源。本电路采用反激式拓扑,连续电流工作模式,电源管理IC设计在电源的副边,由ELAN公司的EM78P258N单片机模拟,是用可编程器件模拟电源管理IC,实现智能电源低成本化的一次成功尝试,通过对单片机的软件设计实现了充电电源的状态显示、充电时间控制、报警、过温保护、过压保护、过流保护等功能。本充电器真正的实现了铅酸蓄电池的三段式充电过程,其最高输出功率可达90 W,效率约85%,成本不到20元,具有很高的市场竞争力。 Abstract:  In order to extend the life of lead-acid battery efficiently and supervise the charging process meanwhile, a 36V lead-acid battery charge powe supply controlled by microcontroller is designed. The charger is flyback switching power supply and works in CCM mode. A EM78P258N microcontroller made by ELAN microelectronics corporation is used as power management IC which is designed at the secondary circuit. The project is a successful attempt to low-cost intelligent power used microcontroller simulating power management IC. The charger also has the functions of the status reveal, charge time control, alarming, thermal protect, current limit and overvoltage protect by the software design. The circuit actually implements the three-step charge process, whose power is up to 90W and whose efficiency can get 85%. The net cost of this charger is less than 20 RMB, so that the charger is of powerful market competitiveness.

  • ISP单片机实验板学习

    学习单片机离不开实验,以往单片机的实验往往依赖于仿真机和单片机学习系统,价格 昂贵,至使学习单片机的门槛很高,很多人不能跨入单片机学习的大门。近年来,随着FLASH 型单片机的广泛应用,采用软件模拟加写片验证成为一种经济实用的实验方法,尤其是随着 单片机技术的发展,很多单片机都具有了ISP 功能,只要一根下载线即可以编程。STC 单片 机更是将其ISP 功能发挥极致,只要有RS232 接口,不需任何其他电路即可实现ISP 功能。。 多年前,本网站为单片机爱好者设计了实验电路板,并公开了全部的软、硬件资料,广 受爱好者欢迎,很多人使用这块实验电路板学习并由此入门,同时网络上也出现了很多同类 功能的实验电路板,为广大爱好者学习单片机创造了良好的条件。
