针对光伏并网逆变器LCL 滤波器的大纹波电流和高频谐波损耗问题,分析了电感之和、电感比值和滤波电容值、谐振频率以及入网电流之间的关系,提出了一种LCL滤波器参数最优设计方法.分析了LCL滤波器的传递特性并建立了谐波等效模型,研究了滤波参数对谐振频率以及并网电流的影响,根据LCL滤波器的设计约束条件和光伏并网逆变器实例设计了一组最优参数,并进行了仿真研究.结果表明,提出的优化方案不仅能够有效抑制开关频率的高频纹波,还能减小电感取值和阻尼损耗.

Mastering Qt 5 English | 6 Feb. 2017 | ISBN: 1786467127 | 575 Pages | AZW3/MOBI/EPUB/PDF (conv) | 25.28 MB Key Features Unleash the power of Qt 5 with C++14 Integrate useful third-party libraries such as OpenCV Package and deploy your application on multiple platforms Book Description Qt 5.6 is an application development framework that provides a great user experience and develops full-capability applications with OpenGl/ OpenGL ES graphics acceleration. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped. What you will learn Create stunning UIs with Qt Widget and Qt Quick Develop powerful, cross-platform applications with the Qt framework Design GUIs with the Qt Designer and build a library in it for UI preview Handle user interaction with the Qt signal/slot mechanism in C++ Prepare a cross-platform project to host a third-party library Develop a Qt application using the OpenCV API Use the Qt Animation framework to display stunning effects Deploy mobile apps with Qt and embedded platforms
