摘　　要： 首先阐述了五相矩阵变换器的结构及其常规的空间矢量调制技术,然后提出了一种新的调制策略。该策略目的是使变换器逆变侧的广义零序子空间合成电压为零,从而使五相矩阵变换器逆变侧的输出电流谐波尽可能的减小。通过常规调制策略和提出的调制策略的仿真结果进行对比,验证了新方法的优点和可行性。 Firstly the conventional space vector modulation technology of five-phase matrix converter was presented in detail. Then a novel modulation strategy was proposed. The key of the proposed modulation strategy is to reduce the complex voltage to zero in the generalized zero sequence sub-space of inverter side. By using the new strategy, the output currents harmonic for the five-phase matrix converter is reduced as soon as possible. The simulation results of the conventional and novel strategies have been carried out which demonstrate the advantages and feasibility of the proposed modulation strategy.
