|Outline of Final Research Achievements
In this study, we have conducted a comprehensive research on wireless power transmission by magnetic resonance with emphasis on cancellation technology. The main research results are leakage field suppression, cross-coupling cancellation technology, and metal particle detection.
For the leakage field suppression, which is the main subject of this project, we demonstrated a compact design that makes effective use of ferrite as an extension of the concept of near field suppression, and a method that is completely different from the concept of near field suppression. We also extended the existing cross-coupling canceling technology. From the viewpoint of safety, it was necessary to expand the existing technological field, and we also conducted research and development on the detection of metallic foreign objects in the air as an application of sensing technology.
