Balancing three-level neutral point clamped inverter DC bus using closed-loop space vector modulation: real-time implementation and investigation

In this study, a real-time controller implementing closed-loop space vector modulation (CLSVM) technique combined with DC bus voltage control is applied on a three-phase four-wire three-level neutral point clamped (NPC) inverter to be used in sustainable energy conversion systems with higher efficiency and lower switching frequency than conventional two-level inverters. The redundant switching sta...
