Outline of Final Research Achievements

This research proposes the digitalization of electric power by applying wide bandgap power devices, which have physical advantages over Si and other materials, and establishes the underlying technology. Small-capacity power supplies, including rechargeable batteries, are distributed in a transmission network to realize series, parallel and arithmetic techniques under the digitalization of power. Since wide bandgap semiconductor power devices can be applied to power control of systems with small capacities in the order of kW, their digital drive and control technology is key. Through the study, digital active gate drive technology, digital power transmission control technology and digital power arithmetic processing technology were investigated, and it was shown that the digitalization of power is feasible.

Academic Significance and Societal Importance of the Research Achievements

本研究は,ワイドバンドギャップ半導体パワーデバイスによる電力のデジタル化を実現するため,スイッチング動作のデジタル駆動,出力の電力パルスによる時分割駆動,密度演算による電力供給技術の実現を図っている.1MHz以上の高速・高周波スイッチングにおいて,スイッチング過渡状態の制御とデバイスごとのチューニングを排除したスイッチング特性を揃える技術を開発し,アナログ回路のチューニングをソフトウェアによる駆動信号の最適化に置き換える技術を確立し,その有効性を示した. 電力パルスを用いた電力のデジタル化を検証し,モータの駆動,無線電力伝送との融合を実証し,デジタル化による電力伝送技術の新しい方向性を示した.
