This paper analyses a three-to-fi
ve phase matrix converter to supply fi
ve-phase
two-motor drive topology. It proposes simple direct duty ratio based pulse-width modulation (PWM)
technique of a three-to-fi
ve phase matrix converter supplying a series/parallel connected fi
ve-phase
AC motor drive system. The developed modulation technique is based on the comparison of a high
frequency carrier signal with the duty ratio of the modulating signals. The major aim of the PWM
is to generate two independent fundamental frequency components that will subsequently control
the two series/parallel connected fi
ve-phase motors independently. The viability of the proposed
control techniques is proven using analytical, simulation and experimental approaches.
