Feasibility and performance analysis of a high power drive based on four synchro-converters supplying a twelve-phase synchronous motor

In this paper a high-power electric drive based ona quadruple-three-phase synchronous motor and four LoadCommutated Inverters (LCI) is investigated to evaluate itsfeasibility and performance. Based on accurate simulationanalyses, the advantages of the proposed solution comparedto the technologically-proven dual three-phase scheme arehighlighted in terms of torque quality and motor efficiencyimprovement.
