Introduction of Wireless Power Transfer

Wireless power transfer WPT) for a broad range of applications is projected to have an exponential growth, with an enormous number of new devices and products to be enabled by this powerful technology. In this chapter, the background and motivations of WPT are introduced first. Then high-level considerations on WPT such as operation frequencies, WPT regulations and WPT standards are reviewed and summarized. In addition, design perspectives on the WPT circuits and systems are also examined. Finally, we present the organization of this book and provide some reading guidelines.
