In order to reduce the complexity of multilevel voltage space vector modulation （SVPWM） in practical implementation，and improve the real-time performance of multilevel converter system，in this paper，by combining the advantages of phase shift pulse width modulation（PS-PWM） and carrier disposition PWM（PD-PWM），a novel multilevel SVPWM implementation based on carrier configuration is proposed，which can improve the utilization of the DC voltage，reduce the total harmonic distortion（THD） of the output and improve the time complexity of the algorithm，which means the novel algorithm can be easily applied to any level cascaded H bridge converters. In addition，the novel algorithm ensures the power balance between each unit，which keeps the advantage of the modular design. Finally，the effectiveness of the proposed modulation strategy is verified by simulation and experiment.
