| Outline of Final Research Achievements |
A Capacitor-Less AC-AC Converter (CLAAC) for a Variable Speed Wind Power Generation System (VSWPGS) using a Switched Reluctance Generator (SRG) has been proposed. As a new type of converter, the CLAAC was developed based on a matrix converter. The CLAAC can be applied to the SRG with independent coils. The CLAAC undertakes the role of controlling the power between the SRG and an electric system in the VSWPGS. Furthermore, a novel control algorithm for the CLAAC to regulate the rotational speed of the SRG has been proposed. The rotational speed controller based on the proposed control algorithm improves the power generation efficiency of the SRG for changes in wind velocity. The VSWPGS using CLAAC and the SRG is modeled with Matlab/Simulink. The modelling considers a mechanical model including a wind turbine, the SRG, the CLAAC, and a controller. Simulation results for wind velocity changes were shown to verify the performance of the proposed VSWPGS using the CLAAC and SRG.

| Academic Significance and Societal Importance of the Research Achievements |
SRGとCLAACを用いるVSWPGS（提案方式）は、レアアースを使用しないので風力発電設備製造における環境負荷を下げ、更に風力発電設備コストを抑制できる。また大容量キャパシタを使用しないので、メンテナンスコストを抑えることができ、更にキャパシタ充電の必要がなく設備起動時間を短縮できるので、設備稼働率を改善できる。提案方式は、小容量の再生可能エネルギー発電設備を需要家の近くに配置する分散型電源への応用が可能であり、2050年カーボンニュートラルの実現に寄与することが期待される。
