| Outline of Research at the Start |
本研究では，外部の補償回路を用いずに，小形化・低コスト化を狙い，誘導機自体で不平衡電圧の補償を行いながら駆動して誘導機の停止や故障の課題を解決できる不平衡電圧補償機能付き誘導機を提案する。シミュレーションと実験により，不平衡電圧に対する補償精度，補償限界を明らかにし，不平衡電圧補償ありとなしの場合で，従来の誘導機と発熱およびトルクリプル比較し，不平衡電圧補償機能付き誘導機の適用効果を明らかにする。

| Outline of Final Research Achievements |
In this research, we proposed an induction machine with a voltage unbalance compensator which continue to drive even if the voltage unbalance occurs without outside voltage compensator such as SVC and STATCOM. We clarified that the voltage unbalance compensator using a method of symmetrical components keeps motor currents balanced and suppress torque ripple for a 750 W induction machine by simulation. In addition, it was conducted that output voltage of the voltage unbalance compensator was observed in the experiment. Now, we continue to do experiment to clarify the effectiveness the voltage unbalance compensator.
