基于三相参考电压独立控制的共直流母线双三电平逆变器驱动开口绕组永磁同步电机不连续调制算法

This article proposes a novel modulation strategy forthe open-end winding permanent magnet synchronous motor (OEW-PMSM) fed by dual three-level inverters with common dc bus. First, by constructing a virtual orthogonal zero-sequence current, the tracking of the sinusoidal signal is transformed into the tracking of the dc signal, which improves the performance of suppressing the zero-sequence curren...
