基于Sigma-Delta调制器的五相高频电压源逆变器新调制策略

This article proposes a new modulation strategy for a five-phase high-frequency voltage source inverter (VSI) based on sigma–delta ($\Sigma \Delta$) modulators. This modulation strategy of five-phase large–medium-zero vectors $\Sigma \Delta$ (5P-LMZV-$\Sigma \Delta$) applies the same switching states as the two large and two medium space vector modulation (2L+2M SVM). Because $\Sigma \Delta$ modul...
