“…In [113] a fault-tolerant ship propulsion drive is proposed and tested by computer simulations. The system is based on a double threephase induction motor supplied by a nine-switch VSC (in place of two six-switch bridge VSCs) and is able to operate also in case of fault of a switch or of a motor phase winding.…”

“…Therefore, 0° symmetrical six-phase induction motor with NSI becomes the preferable choice. The implementation of fieldoriented control on the NSI based six-phase drive is discussed in [19,20]. The direct torque control (DTC) is well known for its simpler structure, faster dynamic performance and robustness against parameter variations [21], as it has no coordinate transformation and no inner proportional-integral (PI) current loops.…”

This paper presents the implementation of direct torque control (DTC) algorithm on the symmetrical six-phase (0°d isplaced) induction motor supplied by nine-switch inverter (NSI). This configuration provides the better dc bus utilisation in comparison to symmetrical 60° displaced and asymmetrical six-phase induction motor. In the conventional topology, 12-switch two-level inverter is required to control the drive where total 64 switching states are available. In the proposed system, NSI is used to drive the motor which is having 27 switching states. The DTC algorithm is proposed with five-level torque comparator by using large, small and zero voltage vectors for reduction in torque ripples. The elimination of xy-subspace flux without affecting the merits of conventional DTC is achieved by using redundant switching states of the inverter. The experimental results under steady-and dynamic-state operation are provided with DTC algorithm on 0° displaced symmetrical six-phase motor supplied by NSI to validate the effective controlling.
