- 2009-2011年度科学研究費助成事業(科学研究費補助金(基盤研究(C)))研究成果報告書 課題番号：21560307 研究代表者：山本吉朗 (鹿児島大学大学院理工学研究科(工学系)准教授)燃料電池を電源とするシステムに研究代表者が提案したバッテリ－電気二重層キャパシタ直列方式の回生エネルギー吸収回路を適用し，永久磁石（PM）モータシステムの効率向上を目的として，基本設計を行った。燃料電池特性や最適動作点，最適な電気二重層キャパシタの個数などを明らかにし，提案システムを市販の高齢者用電動カートに適用する場合のシミュレーションにより，減速時には速度が遅いために回生エネルギーはほとんど回収できないが，連続する下り勾配であれば回生エネルギーが回収できることを示した。The regenerative circuit had been presented by the representative of this research was added to a fuel cell excited inverter system for PM motor drive in order to raise the system efficiency. And characteristics and optimal operating point of our fuel cell and most suitable number of electric double layer capacitor were investigated. Furthermore, proposed system was applied to a commercially available electric cart for elderly people in simulation. The simulated results showed that regenerative energy was hardly able to be absorbed in case of decelerating period because of lower cart speed but was able to be absorbed in case of continuing downhill slope.
