Modulation Restraint Analysis of Space Vector PWM for Dual Three-Phase Machines Under Vector Space Decomposition

open access: yesIEEE Transactions on Power Electronics, 2021
For dual three-phase machines, vector space decomposition allows the control of fundamental and main harmonic components in αβ and xy subspaces, respectively. However, the modulation of voltage references in the two subspaces using the space vector pulsewidth modulation (SVPWM) is not independent but coupled.
