Outline of Final Research Achievements

The purpose of this research is to systematize theoretically the ultra-high frequency switching technology which enables the frequency of power supplies to be increased from tens of kHz to hundreds of MHz by injecting harmonic currents, and to achieve high efficiency stably by applying optimization design. Specifically, we developed a theoretical analysis model by combining our original optimization design technology and steady-state analysis technology that can handle systems with harmonic components. Using this model, we established a high-precision and high-efficiency design technology that does not require any parameter tuning and established the basic theory of ultra-high-frequency and high-efficiency switching power supply design.

Academic Significance and Societal Importance of the Research Achievements

本研究で具現化したスイッチング技術の与える波及効果は極めて大きい。電源回路の革新的小型高効率化はあらゆる電子機器の小型化、薄型化につながる。さらに小型化の恩恵を活用すると、電源回路の分散処理を通じた次世代電気電子システムへつながる。電源回路の超小型化により、ロボット、自動車等閉じた空間の中で、電力をシームレスにかつ、きめ細やかに制御できる次世代パワーエレクトロニクスへと高度展開するポテンシャルを持つ。さらに、パワーエレクトロニクス分野の多岐に渡るアプリケーションへの適用が期待され、エネルギー利用効率の向上に貢献するだけでなく、電気電子分野に対する領域の枠を超えた革新的インパクトを与える。
