Modulation Technique Design of An Improved Zero Common Mode Voltage (CMV)
Journal of Physics: Conference Series, 2023 Abstract Voltage imbalance of neutral-point and CMV are hot issues in the research of three-level inverters. This paper first introduces the three-level topology of the neutral-point clamped (NPC) inverter. Aiming to eliminate CMV of three-level NPC and balance the voltage of the neutral point simultaneously, a virtual space vector pulse
