利用基于空间矢量的最优混合PWM降低五相电压源逆变器谐波畸变

Compared with three-phase motors, multiphase motors offer several advantages such as higher efficiency, lower torque pulsation, and higher fault tolerance. To exploit these advantages, a multiphase modulator with low current harmonics is essential. However, the switching sequence of conventional space-vector pulse width modulation (SVPWM) is not optimal because of high stator flux ripple, which is...
