In motor drive systems utilizing voltage source inverters (VSIs), common-mode voltage (CMV) can cause insulation degradation and bearing damage, ultimately reducing system reliability and operational lifespan. With the increasing adoption of model predictive current control (MPCC), CMV mitigation has become a key research focus to enhance performance and longevity. Conventional predictive current control schemes inherently generate significant CMV due to the application of zero-voltage vectors (ZVV), which accelerates bearing deterioration. However, eliminating ZVV can effectively suppress CMV but introduces high dv/dt variations and increased total harmonic distortion (THD) in the stator current. To address these challenges, this paper proposes a modified MPCC strategy with centroid-based vector averaging method that ensures an average CMV of zero while reducing dv/dt variations and improving current quality. The proposed approach leverages a multi-vector generation strategy based on virtual voltage vectors, thereby avoiding the use of zero vectors while maintaining optimized performance. Simulation and experimental results validate the effectiveness of the proposed control method in reducing CMV, minimizing current distortions, and enhancing system stability in induction motor (IM) drives.
