    Wireless power transfer (WPT) is believed to be one of the most promising technologies with wide application prospect. It has superior flexibility and portability over conventional wired power transfer. WPT is a fundamental technology that can be used by various electronic products. The flexibility and new usage scenario introduced may have profound impact on the whole CE industry. However, the existing induction-based WPT technology has the limitations of short charging distance, high position alignment and single loading per device, etc. Therefore, a more advanced and long-term WPT solution is desired by the industry. This project aims to develop the medium-range power transfer solution based on magnetic resonant coupling theory. The deliverables consist of 4 key technologies: automatic impedance matching (sensing component, matching circuit and control algorithm); resonator with uniform magnetic field generation; wireless quick charge circuit and Tx/Rx IC for higher power wireless charging. The reference design of the WPT module has a targeted performance of transmission power bigger than 33W, charging distance larger than 15cm, and supporting multiple device simultaneously charging. It will become a wireless power technology platform for various electronic products and applications. Wireless power transfer product is a rapid growing market worldwide. The market size is forecasted to exceed 12 Billion dollar by year 2020. The WPT module to be developed in this project can be installed in home or in public area to provide charging function for the end users; it also can be embedded in various wearable electronics, portable devices, smart manufacturing facilities as well as electronic cars. It will bring big economic returns and social benefits to both local and overseas industries.
