基于逆变级采用零电压矢量时整流级有功电流矢量幅值为零，且6个有功电流矢量可任意选择的特点，提出了一种用于间接矩阵变换器的新型非连续脉宽调制（DPWM）策略，以降低共模电压（CMV）。在该DPWM策略中，整流级的参考电流矢量由两个相邻的有功电流矢量合成，逆变级的参考电压矢量由两个相邻的有功电压矢量和一个零电压矢量合成。当在逆变器级中使用零电压矢量时，使用两个相邻有功电流矢量中具有最低输入相电压的适当有功电流矢量来产生较低的CMV。在开关损耗相同的情况下，与传统SVM相比，该策略具有更好的输入性能和更好的高电压传输比输出性能。最后通过仿真和实验验证了该调制策略的有效性。
Based on the characteristics that the amplitude of active-current vector in the rectifier stage is zero when the zero-voltage vector is used in the inverter stage, and any one from the six active-current vectors can be selected, a novel discontinuous pulsewidth modulation (DPWM) strategy for the indirect matrix converter is proposed in this article to reduce the common-mode voltage (CMV). In this DPWM strategy, the reference current vector in the rectifier stage is synthesized by two adjacent active-current vectors, and the reference voltage vector in the inverter stage is synthesized by two adjacent active-voltage vectors and one zero-voltage vector. When zero-voltage vectors are used in the inverter stage, an appropriate active-current vector with the lowest input phase voltage among the two adjacent active-current vectors is used to produce a lower CMV. Under the same switching loss, the proposed strategy has a better input performance and better output performance in high voltage transfer ratio than conventional SVM. Finally, the effectiveness of the modulation strategy is verified by simulation and experiments.
