Outline of Final Research Achievements

Novel theory for wireless power transfer (WPT) which consistently explains power-electronics based WPT system and microwave-technology based WPT system is established.
Power electronics theory for WPT has a limitation of treating distributed circuit. It's difficult for microwave theory to adopt WPT system because load impedance varies due to a demand of user, or load requires constant voltage. The proposed unified theory can treat these systems, which enables us to combine power-electronics technology and microwave technology for WPT.

Academic Significance and Societal Importance of the Research Achievements

無線電力伝送の実用化が期待されているが、さらなる伝送効率・伝送距離の向上が必要である。現在、無線電力伝送技術は、パワーエレクトロニクス技術に基づくものと、マイクロ波技術に基づく物に大別される。それぞれの技術に基づいたWPTシステムが提案されているが、実用化のためには両者を融合することにより、より高効率で長距離を伝送可能なWPTシステムの開発が必要である。本研究は、従来は全く独立した体系を持つパワーエレクトロニクス理論によるWPTとマイクロ波技術によるWPTを統一的に説明できる理論を構築することにより、より一層の両者の融合の促進が期待される。
