All switching converter topologies, operating from a grounded utility system and feeding a floating output system, create common mode voltages that are present on the load equipment. This paper develops a systematic analysis on the common mode voltage in various converter topologies typically used in AC drives, including two-level VSI (voltage source(More)
Space vector modulation (SVM) is increasingly used in three-level neutral point clamped (NPC) inverters. However, the conventional SVM scheme produces even order harmonics in the inverter output voltages. We analyze the mechanism of even order harmonic production. A new SVM scheme, which can eliminate all the even order harmonics, is proposed. The(More)
