I am presenting this novel book on advances and trends in power electronics and motor drives to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer- sity professors, and even graduate students that my other books in this area have. Unlike the traditional books available in the area of power electronics, this book has a unique presentation format that makes it convenient for group presentations that use Microsoft’s PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is ready for presentation with the core figures. Presentations can also be organized using just selected portions of the book

電力電子系統的集成化是現今電力電子技術發展的趨勢，系統的模塊化和標準化技術是目前電力電子領域的重要研究方向。研究基于電力電子網絡的變流系統，對復雜電力電子裝置的系統級集成具有重要意義，是電力電子系統集成技術的基本組成部分。本文從變流系統的功率流和信息流雙重分布性的角度出發。對電力電子系統網絡（power electronics System Network，PES—Net）的模型和變流系統的通信需求進行分析，提出實時電力電子系統網絡（Real—time power electronics system network，RT—PES—Net）；并對基于新網絡的分布式控制及管理方案和模塊化軟件方案等內容進行系統的研究，提出基于棧操作的實時軟件構建方案。本文的研究將為變流系統的控制結構和軟件方案標準化提供參考和理論依據，為應用系統的集成提供解決方案。 復雜中大功率變流系統是網絡化分布式控制系統的應用對象。首先，論文以復雜系統為研究對象，分析了應用系統的功率流和信息流在空間結構上的對偶關系和雙重分布的特性；在電力電子集成模塊（power electronics Building Blocks，PEBB）的基礎上，研究了變流系統的網絡化分布式控制方案，并得出系統組構的初步構想，總結出適合復雜電力電子系統集成的標準化理論。 接著，論文對電力電子網絡模型進行了研究。分析了現有各類總線網絡和目前用于電力電子應用系統的網絡，從結構、速率和協議等各個方面將兩類網絡進行了系統的對比。明確了電力電子系統網絡（PES—Net）的定義，分析并總結復雜電力電子實時系統所需網絡必需具備的條件。根據現有網絡技術背景，綜合控制結構和網絡需求，提出了電力電子系統網絡（PES—Net）的模型。 為滿足變流系統的實時控制，論文對分布式控制結構的通信需求進行了研究。以網絡控制系統（Networked Control System，NCS）為背景，對變流器系統控制信息延時因素進行了分析；通過對典型電力電予系統的分析，歸納和總結了系統的控制功能和控制內容，對系統不同層次的控制任務進行了響應時間需求分析和網絡的分層配置；通過對仿真結果的分析，研究了應用系統內模塊控制信息延時對不同應用系統的性能影響和對開關頻率的限制。根據變流系統對控制延時的接受程度，將電力電子復雜系統歸為兩大類：1）零延時系統；2）定延時系統。針對上述兩類系統，論文給出了電力電子網絡（PES—Net）的通道容量和應用系統開關周期的計算方法。 論文對開放式、分布式的電力電子系統網絡（PES—Net）的硬件組成和同步方案進行了研究，提出新的實時網絡和系統級集成方案。根據主節點和從節點的控制任務需求，分別從功能和系統結構的角度對開放式網絡的硬件構成進行研究；根據控制系統的接口需求分析，對節點的通用性設計進行重點討論。針對網絡的同步問題，本文分析了簡單有效的解決方法，即基于數據結構的同步補償方案；此外，論文提出基于實時高速電力電子系統同絡（RT-PES-Net）的同步方案，研究適合變流器實時控制的網絡結構和相應的硬件配置。根據應用控制和通信系統所需的各種操作，論文對實時網絡的管理進行了討論，研究了信息幀管理和相應的硬件設置，并對各種工作模式下所需的通信時間進行了計算和比較。基于實時網絡系統及其管理方案，論文給出了組構以PEBB為基礎的變流系統的方案。 論文對基于RT-PES-Net的模塊化軟件方案進行了研究。首先，將控制軟件與功率硬件進行解耦，使得軟件設計與硬件部分分離。在分析電力電子軟件特性的前提下，論文提出基于棧操作的模塊化軟件方案，增加子程序實時構件的內聚性；對軟件模塊化的通用性進行研究，分析模塊接口參數和變量的申明和配置，并研究參數的定標，對構件進行分類；分析子程序實時構件在執行速度上的優點。論文對電力電子系統控制軟件（Powerr Electronics System Control Software，PES-CS）的組構和集成進行研究，簡化軟件主框架。 最后，論文分別對RT-PES-Net和模塊化軟件方案進行了相應的實驗研究和分析。論文對提出的實時電力電子系統網絡（RT-PES-Net）進行了通信實驗，將新網絡拓撲對變流系統的延時影響與舊網絡系統的延時影響進行比較，總結新網絡系統在控制實時性、提高開關頻率、網絡可擴展性和管理靈活度等方面的優勢。論文針對RT-PES-Net進行應用研究，驗證該網絡可解決網絡通信失步所造成的問題。論文對基于通用型實時構件和棧操作的模塊化軟件方案進行實驗驗證，為標準化軟件庫的建立和系統級集成提供參考方案。 網絡化的控制結構研究是復雜電力電子系統級集成研究的關鍵。本課題針對復雜變流系統提出了實時電力電子系統網絡（RT-PES-Net），并以該網絡為基礎對分布式控制結構及相應的網絡化管理方案和模塊化軟件方案展開一系列研究，為電力電子控制系統提供標準化、開放式的網絡參考體系，并以此結構來快速構建終端復雜變流系統，為實現標準的應用系統組構提供參考方案，有助于解決電力電子標準化推廣所面臨的難題。論文為應用系統的即插即用和動態重構提供了研究基礎，從而為最終實現復雜變流器的應用系統級集成提供系統化的理論和方法依據。同時，論文的研究開拓了電力電子系統集成和標準化研究的一個新方向。

Advances in low power electronics now allow placementof battery-powered sensors and other devices in locationsfar from the power grid. Ideally, for true grid independence,the batteries should not need replacement, but instead berecharged using locally available renewable energy, suchas solar power. This Design Note shows how to producea compact battery charger that operates from a small2-cell solar panel. A unique feature of this design is thatthe DC/DC converter uses power point control to extractmaximum power from the solar panel.

This book is intended for researchers, teachers, and students willing to ex- plore conceptual bridges between the fields of Automatic Control and Power Electronics. The need to bring the two disciplines closer has been felt, for many years, both by power electronics specialists and by Automatic Control theorists, as a means of fruitful interaction between the two scientific com- munities. There have, certainly, been many steps given in that direction in the last decade as evidenced by the number of research articles in journals, special sessions in conferences, and summer courses throughout the world.

The first edition of the book was one of the elements of my habilitation (a quali- fication above a Ph.D., which is a necessary step for obtaining the title of a professor in Poland and other European countries), and as a result it was subse- quently very carefully reviewed by four reviewers. The habilitation was a success. Using the insightful comments from my reviewers, I have improved the current version and eliminated some typographic errors that were initially overlooked.

Switched systems are embedded devices widespread in industrial applications such as power electronics and automotive control. They consist of continuous-time dynamical subsystems and a rule that controls the switching between them. Under a suitable control rule, the system can improve its steady-state performance and meet essential properties, such as safety and stability, in desirable operating zones.
