Research Abstract

This research has dealt with a three-phase modular multilevel converter that is considered as one of the next-generation multilevel converter. This research has focused on its application to a medium-voltage motor drive with fans or blowers, in which the load torque is proportional to the square of the rotating speed. Also, this research has attempted to control negative-sequence reactive power by using a STATCOM based on the MMC. The validity of the motor drive and the STATCOM has been confirmed by experiment.
