利用C语言开发的u盘文件系统的开发资料，系统引导记录（DBR）的数据结构

说明：  LaTeX（LATEX，音译“拉泰赫”）是一种基于ΤΕΧ的排版系统，由美国计算机学家莱斯利·兰伯特（Leslie Lamport）在20世纪80年代初期开发，利用这种格式，即使使用者没有排版和程序设计的知识也可以充分发挥由TeX所提供的强大功能，能在几天、甚至几小时内生成很多具有书籍质量的印刷品。对于生成复杂表格和数学公式，这一点表现得尤为突出。因此它非常适用于生成高印刷质量的科技和数学类文档。这个系统同样适用于生成从简单的信件到完整书籍的所有其他种类的文档(Latex (latex, transliterated "LATECH") is a typesetting system based on "X", which was developed by American computer scientist Leslie Lambert Lamport was developed in the early 1980s. Using this format, users can give full play to the powerful functions provided by tex even if they have no knowledge of typesetting and programming, and can generate a lot of book quality prints in a few days or even hours. For generating complex tables and mathematical formulas, this is particularly prominent. Therefore, it is very suitable for generating high quality technical and mathematical documents. The system is also suitable for generating all kinds of documents, from simple letters to complete books)

提出一种基于电压电流双环控制的三相SVPWM 逆变器,分析了其两相同步旋转坐标系下的数学模型 并由此构建了系统的电压电流控制器。为了提高系统的动态响应特性及抗扰能力,电压外环包含了负载电流前馈 及输出滤波电容电流解耦,电流内环包含了输出电压前馈及输出滤波电感电压解耦。20 kVA实验样机的实验结果 表明,该逆变器具有良好的非线性负载能力。(A dual-loop control of voltage and current-based three-phase SVPWM inverter, an analysis of its two-phase synchronous rotating coordinate system and thus build a mathematical model of the system voltage and current controller. In order to improve the system dynamic response and anti-interference ability, voltage ring contains load current feedforward and output filter capacitor current decoupling, current loop includes the output voltage feedforward and output filter inductor voltage decoupling. 20 kVA experimental prototype of the experimental results show that the inverter has a good non-linear load capacity.)
