Abstract
  • Wireless power transfer (WPT) is a way to transfer power from one device to another without any wire or cable connections. Although the technology has been around for more than 100 years, it is gaining popularity in recent years due to the ever-increasing demand for faster and more frequent charging of various consumer electronics devices such as electric vehicles, medical implants, and wireless sensors. Due to their relatively high-power transfer efficiency, freedom of movement and radio-frequency (RF) safety concerns, loosely coupled, inductive, wireless power-transfer technologies are the most promising category of battery-operated devices. Though tightly coupled systems with well-established design rules and system parameters have been used in industry and discussed in literature for decades, the same does not hold for loosely coupled systems. The system is a complex system with dynamic parameters that may require sophisticated control and tuning features. This dissertation presents various studies of loosely coupled, wireless power-transfer systems, specifically in RF front end.
