The aim of this project is to research a novel high-order nonlinear resonance wireless power transfer (WPT) approach for implementation in practical position-agile WPT applications ranging from dynamic and opportunistic electric vehicle (EV) charging to powering biomedical devices. Inductive coupling near-field WPT is an emerging technology with an immense potential for a wide range of applications. WPT systems use dedicated sources or transmitters for contactless electrical power transfer at different power levels ranging from milliwatts to kilowatts. Although some commercial products have adopted WPT technology, the technology remains underdeveloped because of the limitations imposed by sensitivity to alignment and position in current WPT systems. For example, in wireless EV charging, the system's sensitivity to vehicle's tire size, speed, and position could significantly degrade power transfer efficiency. This project will develop a new position-agile WPT technology based on high-order nonlinear resonance, founded on a unique topology. The new WPT technology offers an effective solution to address the sensitivity of WPT efficiency without any complex feedback or sensor circuitry requirement. Within the field of biomedical devices, when wirelessly powering implants, this approach provides a robust WPT solution that does not hinder patient's mobility and can wirelessly power a host of biomedical devices, which not only improves patients' lives but also reduces the burden
