An improved seven-phase SVPWM modulation strategy based on virtual voltage vectors
Energy Reports, 2023 Seven-phase motors are usually powered by seven-phase voltage source inverter. The traditional seven-phase SVPWM algorithm produces a large common-mode voltage (CMV), while harmonic currents in the harmonic subspace can also produce large harmonic losses

Improved virtual space vector modulation for neutral point voltage oscillation and common-mode voltage reduction in neutral point clamped three-level inverter [PDF]
Archives of Electrical Engineering, 2021 The neutral point clamped (NPC) three-level inverter is widely used in highvoltage and high-power applications. However, neutral point voltage oscillation (NPVO) and common-mode voltage (CMV) problems exist in the NPC three-level inverter. In this paper,

Model Predictive Control of Six-Phase Induction Motor Drives Using Virtual Voltage Vectors [PDF]
IEEE Transactions on Industrial Electronics, 2018 The most serious and recent competitor to the standard field oriented control for induction motors (IM) is the finite control set model predictive control (FCS-MPC). Nevertheless, the extension to multiphase drives faces the impossibility to simultaneously regulate the flux/torque and the secondary current components (typically termed $x-y$ in the ...

IEEE Open Journal of Circuits and Systems, 2022 The Conventional model predictive control (C-MPC) uses only a single voltage vector in each control period, resulting in poor control performance. In addition, the computational burden in discrete space state generated by three-level inverter cannot be ...
