201634789 吴亮 光伏系统中蓄电池的充电保护IC电路设计 μm数字CMOS工艺对电路进行仿真分析。在对电路做整体仿真时，主要观察的是保护模块对电池的充放电过程是否通过监测Vdd电位和Vm电位而使芯片的CO端和DO端发生相应的变化。图7所示的整体仿真波形图是保护模块随着电池电压的变化从通常工作模式转换到过充电模式，然后回到通常工作模式，接着进入过放电模式，最后再回到通常工作模式。由于本设计处于前期阶段，各个参数还需要优化，只是提供初步的仿真结果。 6.结论 设计了一种集蓄电池充电与保护功能于一身的IC。利用此设计既可以减小而积，又可以减少外围电路元器件。电路同时采用了低功耗设计。由于此项目正在进行设计优化阶段，完整的仿真还不能达到要求，还需要对各个模块电路进行优化设计。 英语原文 Design of a Lead-Acid Battery Charging and Protecting IC in Photovoltaic System 1.Introduction Solar energy as an inexhaustible, inexhaustible source of energy more and more attention. Solar power has become popular in many countries and regions, solar lighting has also been put into use in many cities in China. As a key part of the solar lighting, battery charging and protection is particularly important. Sealed maintenance-free lead-acid battery has a sealed, leak-free, pollution-free, maintenance-free, low-cost, reliable power supply during the entire life of the battery voltage is stable and no maintenance, the need for uninterrupted for the various types of has wide application in power electronic equipment, and portable instrumentation. Appropriate float voltage, in normal use (to prevent over-discharge, overcharge, over-current), maintenance-free lead-acid battery float life of up to 12 ~ 16 years float voltage deviation of 5% shorten the life of 1/2. Thus, the charge has a major impact on this type of battery life. Photovoltaic, battery does not need regular maintenance, the correct charge and reasonable protection, can effectively extend battery life. Charging and protection IC is the separation of the occupied area and the peripheral circuit complexity. Currently, the market has not yet real, charged with the protection function is integrated on a single chip. For this problem, design a set of battery charging and protection functions in one IC is very necessary. 2.System design and considerations The system mainly includes two parts: the battery charger module and the protection module. Of great significance
