Six‐phase SVPWM with common‐mode voltage suppression [PDF]
IET Power Electronics, 2018 There are two common‐mode voltages (CMVs) in a six‐phase machine with two Y‐connected windings shifted by 30°, which bring adverse effects on the six‐phase system. In this study, a method of six‐phase space vector pulse width modulation (SVPWM) is proposed, which can suppress the magnitude and frequency of the two CMVs.
