| Abstract |
One of the advantages of multi-phase machine variable-speed drives is the possibility of disturbance-free mode of operation when one or more phases are lost during normal operation. This requires the modification of the control algorithm in post-fault operation. This paper investigates the use of multidimensional space vector PWM technique to synthesise required voltages for the disturbance-free mode of operation of a five-phase machine in post-fault operation. Different cases, with regard to the number and spatial position of faulted phases, are covered, showing the necessary conditions mathematically and enabling examination of the performance of the modulation technique. Simulation results confirm the adequacy of the multi-dimensional PWM approach to control the supply of the machine in the post-fault mode of operation. |
