对Boost升压电路进行设计与性能优化； （2）完成DC变换器环节实现光伏最大功率跟踪硬件电路设计，分析其实现最大功率跟踪控制的理论依； （3）研究实现基于DSP光伏最大功率跟踪的算法，及其控制流程图； （4）选择适合的最大功率跟踪算法，编写软件程序实现光伏电池的最大功率输出，尽可能提高光伏发电系统的效率。(In this paper, I will mainly research the maximum power tracking technology of the PV, design and improve the Boost circuit (Boost cut broken circuit). First, I measuring the electrical characteristics of photovoltaic cells , and get the output characteristics of photovoltaic cells; then based on Boost circuit of implementations, analysis the works of Photovoltaic maximum power tracking. Then, based an the DSP microcontroller TMS320F2812 , I use the method of perturbation and observation ,to do the programming based on C language.)

说明：  OWC是Office Web Compent的缩写，即Microsoft的Office Web组件，它为在Web中绘制图形提供了灵活的同时也是最基本的机制。在一个Intranet环境中，如果可以假设客户机上存在特定的浏览器和一些功能强大的软件（如IE6和Office 2000/XP/2003），那么就有能力利用Office Web组件提供一个交互式图形开发环境。这种模式下，客户端工作站将在整个任务中分担很大的比重。理论上说Excel能做的图都可以通过OWC画。(OWC is an acronym for Office Web Compent that Microsoft' s Office Web components, in the Web in its graphics rendering, while providing a flexible mechanism is the most basic. In an Intranet environment, if the client can assume the existence of a particular browser, and some powerful software (such as IE6 and Office 2000/XP/2003), then it would be able to take advantage of Office Web components to provide an interactive graphical development environment . This mode, client workstations will be shared throughout the task in a large part. Excel can do in theory plans are available through OWC painting.)
