Outline
Aiming at the inherent problems of large common-mode voltage and heavy computation in model predictive current control of the six-phase permanent magnet synchronous motor（PMSM），a model predictive current control method for an open-end winding six-phase PMSM was proposed. Firstly，the neutral point of the six-phase PMSM was opened and two six-phase voltage source inverters were connected to form an open-end winding structure fed by a dual inverter structure，in order to offset the common-mode voltage between inverters. Secondly，a wide range of voltage vectors were fed by a dual inverter，from which the vector with zero common-mode voltage property was selected. On this basis，the harmonic current in the x-y plane and the utilization rate of bus voltage were considered，and the vector set was reduced to a control set containing seven voltage vectors，which reduces the computational burden. Finally，compared with the existing model predictive control method of traditional six-phase PMSM，the effectiveness of the proposed method was proved.
