Abstract :
This paper presents three-phase four-level FLC based electric motor drive for mining application supplied directly from a 6 kV ac-grid. It describes complete control algorithms of the drive with active voltage balancing control. The proposed control is verified by experiments carried out on down-scale drive prototype of rated power of 35 kVA.
