A Study of Synchronous Motor Drive using Static Frequency Converter

SFC (static frequency converter) system has been used as drive of large synchronous machine in many industry applications. But many papers have been presented on the control algorithm of SFC system, not the acceleration and start-up but the rated speed operation with line connection and the braking operation with regeneration which is used in the industry. This paper presents all control algorithms for the large synchronous machine connected with SFC system. The experimental results show that the proposed several algorithms are proper and effective
