Hybrid Voltage Vector Preselection-Based Model Predictive Control for Two-Level Voltage Source Inverters to Reduce the Common-Mode Voltage

Abstract: To suppress the common-mode voltage (CMV) and reduce the current total harmonic distortions (THDs) and ripples of two-level voltage source inverters (2L-VSIs), a hybrid voltage vector (VV) ...
