摘要: Multilevel inverters are being increasingly used for high-power medium-voltage applications. Three-level neutral point clamped (NPC) topology is most widely of multilevel inverters. However, at higher modulation index, particularly in over-modulation region, the fluctuation deteriorates performance inverter. Furthermore, operating inverter lower index implies that it operated voltages only, and installed DC link capacity not fully utilized. This paper proposes a simple space vector PWM scheme three-level NPC indices including with balancing. Experimental results provided.
