To solve the problem of common-mode voltage spikes caused by dead-time in the traditional model predictive pulse pattern control algorithms, an improved model predictive pulse pattern control algorithm was proposed. First, the pulse pattern design approach of the traditional model predictive pulse pattern control algorithm was introduced. Then, the influence of dead-time on this algorithm was analyzed, and the pulse pattern was optimized considering the dead-time effect to eliminate the common-mode voltage spikes generated during the dead-time. Finally, the traditional model predictive control based on common-mode voltage suppression, the traditional model predictive pulse pattern control algorithm and the proposed algorithm were experimentally compared. Experimental results show that compared with the traditional model predictive pulse pattern control algorithm, the proposed algorithm effectively suppressed the common-mode voltage amplitude to one-sixth of DC-side voltage without significantly increasing the total harmonic distortion of current ortorque ripple, thereby eliminating the common-mode voltage spikes during the dead-time.
