| Outline of Final Research Achievements |
The variable speed motors for large capacity and medium voltage are developed. The modular matrix converter for driving a medium voltage variable speed motor has merits of small size and high efficiency because of direct conversion of three-phase voltage to variable voltage without commercial-frequency transformer. In this research, the authors proposed the simple control scheme of the modular matrix converter. The proposed control scheme consists of three controls of input current, capacitor voltage balance and output voltage. These three controls are achieved by positive-, zero-, and negative-phase sequence components of the source currents. The effectiveness of the proposed control scheme was verified by the experiments using the laboratory prototype.
