Control and Filter Design of Single-Phase Grid-Connected Converters A state-of-the-art discussion of modern grid inverters In Control and Filter Design of Single-Phase Grid-Connected Converters, a team of distinguished researchers deliver a robust and authoritative treatment of critical distributed power generation technologies, grid-connected inverter designs, and renewable energy utilization. The book includes detailed explanations of the system structure of distributed generation (DG)-grid interface converters and the methods of controlling DG-grid interface voltage source converters (VSCs) with high-order filters. The authors also explore the challenges and obstacles associated with modern power electronic grid-connected inverter control technology and introduce some designed systems that meet these challenges, such as the grid impedance canceller. Readers will discover demonstrations of basic principles, guidelines, examples, and design and simulation programs for grid-connected inverters based on LCL/LLCL technology. They will also find: A thorough introduction to the architectures of DG-grid interfacing converters, including the challenges of controlling DG-grid interfacing VSCs with high-order filters Comprehensive explorations of the control structure and modulation techniques of single-phase grid-tied inverters Practical discussions of an LLCL power filter for single-phase grid-tied inverters Fulsome treatments of design methods of passive damping for LCL/LLCL-filtered grid-tied inverters Perfect for researchers, postgraduate students, and senior level undergraduate students of electrical engineering, Control and Filter Design of Single-Phase Grid-Connected Converters will also benefit research & development engineers involved with the design and manufacture of power electronic inverters.

IN THE NEWSWeimin Wu: pioneer physicist on Chinese science's turbulent past, promising futureTimes Higher Education, 25 February 2016While the first 30 years of new China's scientific development was a self-reliant era marked by the detonations of the atomic bomb, the hydrogen bomb, and the launch of the first artificial satellite, the second 30 years after the reform and opening up was signified by the introduction of the Internet to China. Weimin Wu is a unique legendary figure whose career spanned both periods. He not only contributed to the bomb and satellite projects, but also sent out the email from China to Switzerland in 1986, which was listed as the first event in the history of China's Internet development. The Tiananmen Square Protest in 1989 changed his life's trajectory, leading him to eventually immigrate to the US. His personal emotional life is also remarkable. With his experiences immersed in both Eastern and Western cultures, Wu came to believe in the convergence theory of social development, which provides a refreshing perspective for the readers. The autobiography records the details of his legendary life stories, from taking pictures with the Chinese leader Mao Zedong, to shaking hands with Deng Xiaoping; from being removed from the Institute of High Energy Physics, to the repealing of his Chinese passport. The story line is full of engaging ups and downs. In that turbulent era, Wu's rich emotional experiences and love stories were also a mirror for the Chinese society, with some details comparable to the plots of suspense novels and movies. The book is well illustrated with many pictures and flows smoothly with a simple writing style. The stories are factual and moving, all too realistic. The author has sincerely revealed his true self to the reader, and at the same time, faithfully described that period of history, giving the reader a grasp on the true workings of history. His comparison of the Eastern and Western cultures, analysis of science and superstition, interpretation of religion and arts, and his 'convergence' theory of social development, are all unique and insightful. This book faithfully tells Weimin's professional and personal life on the cusp and takes readers on a journey to explore true history through an ordinary person's stories.

This book is a labor of love for Dr Wu Weimin whose favorite photography subjects are ordinary events which capture the heart of the common folks. The cameras Dr Wu uses may not be the most sophisticated but the images he has taken are truly striking. His award-winning collections of photographs are very well received worldwide. The introduction written by Dr Rick Vidal of Fermilab was endorsed by Dr Leon Lederman, Nobel Laureate in Physics (1988). Being a physicist by training, Dr Wu was among the pioneer scientists who helped to develop China's first atomic bomb and to launch its first satellite. He also participated in building the first Chinese electron-positron collider. Another extraordinary feat is that he sent out the very first e-mail from China on 25 August 1986.
