一种用于三相串联端绕组永磁同步电机的改进型三维空间矢量调制策略

The series-end winding motors provides a path for zero-sequence current, thereby increasing the degree of freedom of the current. However, the presence of zero-sequence current also causes the voltage vector to be distributed in an irregular 3-D space, making the space vector pulse width modulation (SVPWM) very complex and nonintuitive. Moreover, zero-sequence current also leads to distortion of t...
