This letter presents a new space vector modulation strategy adopting new zero vectors to achieve common-mode current (CMC) reduction for indirect matrix converter (IMC). By substituting conventional zero vectors by new zero vectors, the impedance of common-mode loop increases, which contributes to CMC reduction. Thus, the IMC system with the proposed method alleviates the adverse effects of CMC for ac drives. Moreover, additional hardware and complex commutation process are not required. Experiments are conducted to verify the effectiveness of the proposed method.

一种降低间接矩阵变换器共模电流的新调制策略

这封信提出了一种新的空间矢量调制策略，采用新的零矢量来实现间接矩阵转换器 (IMC) 的共模电流 (CMC) 降低。通过用新的零向量代替传统的零向量，共模环路的阻抗增加，这有助于降低 CMC。因此，具有所提出方法的 IMC 系统减轻了 CMC 对交流驱动器的不利影响。此外，不需要额外的硬件和复杂的换向过程。进行实验以验证所提出方法的有效性。
