Simple FCS-MPC Method for Reducing Common-Mode Voltage in a Three-Phase Two-Level Voltage Source Inverter

Common mode voltage (CMV) causes various issues, including a negative impact on the performance of hybrid electric vehicle’s power system (HEV). Many papers have published methods that mitigate CMV, almost all which attempt to avoid zero vectors, but this increases total harmonic distortion (THD). This work describes simple and efficient method for reducing CMV in two-level three-phase source inverter (VSI) with an RL load. uses only active vectors. It replace vector two opposite vectors V 2 5 . T 1 respectively one sampling period s A numerical simulation, using Matlab-Simulink. is achieved assess effectiveness proposed control technique. The obtained results show reduction THD value (17% improvement) decrease peak from (${{ + {V_{dc}}} \over 2}$ ${{ - 6}$) $\pm {{{V_{dc}}} 6}$. These are compared those by traditional predictive model MPC.
