Pulse width modulation (PWM) strategies for multilevel multiphase ac drives have been analysed in this thesis. The large amount of published work in the area of multiphase drives recognises their advantages compared to the standard three-phase solutions. Some of them arc improved power sharing capabilities, increased reliability and fault tolerance. However, in the most of these works two-level inverters were used for supply of multiphase machine. Also, huge amount of research has been done in the area of multi level inverters. Nowadays, three-phase multilevel inverters are in use in high-power applications. However. the ideal scenario for high-power applications is supply of a multi phase machine from the multilevel inverters. So far no negative consequences of combination of these two topologies, apart from increased complexity of the system, have been identified, and this topology is the subject of this thesis.
