摘要

THE load-commutated-inverter (LCI)-based induction motor drives have been traditionally used in very-high-power applications such as pumps, compressors, and fans drives. The drives are based on economical and reliable current-source inverters (CSIs) using thyristors, and rugged squirrel-cage induction motor. The merits of the LCI-based system result from the fact that it employs converter-grade thyristors and utilizes natural commutation of the thyristors.
