Digital Control in Power Electronics

This book presents the reader, whether an electrical engineering student in power electronics or a design engineer, some typical power converter control problems and their basic digital solutions, based on the most widespread digital control techniques. The presentation is focused on different applications of the same power converter topology, the half-bridge voltage source inverter, considered both in its single- and three-phase implementation. This is chosen as the case study because, besides being simple and well known, it allows the discussion of a significant spectrum of the more frequently encountered digital control applications in power electronics, from digital pulse width modulation (DPWM) and space vector modulation (SVM), to inverter output current and voltage control. The book aims to ser ve two purposes: to give a basic, introductor y knowledge of the digital control techniques applied to power converters, and to raise the interest for discrete time control theor y, stimulating new developments in its application to switching power converters.

汇编语言 教学手册 ＣＨＭ

《汇编语言》(Assembly Language)是计算机专业中一门重要的基础课程，是一种面向机器的低级语言。它依赖于硬件，能通过巧妙的程序设计充分发挥硬件的潜力。汇编语言程序产生的代码运行效率高。因此，到目前为止，许多软件系统(例如操作系统等)的核心部分仍然用汇编语言来编写。 计算机专业所培养的学生，不应仅仅满足于利用他人已开发出来的软件和软件工具来解决实际问题，还应具备有分析、研究原有软件系统，改进、完善、提高原有系统功能供广大用户使用的能力。汇编语言程序设计将使学生受到更严密、更系统的程序设计及其思维方法的训练，为深入分析、研究、开发新的软件系统打下良好的训练基础。 本课程的教学目的是使学生进一步了解计算机的基本组成，汇编指令的格式和使用方法，以及用汇编语言进行程序设计的基本思想和方法。于此同时，希望学生能了解用汇编语言程序来充分发挥计算机性能的基本思想。 本课程的学习也将为后续课程(如操作系统、接口与通信、计算机外围设备等)的学习提供必要的前期知识。
