2nd Prize, 2005 Industrial Power Converter Committee (IPCC) Best Paper Award, IEEE Industry Applications Society (IAS), USAA Simple Space Vector PWM Scheme to Operate a Three-level NPC Inverter at High Modulation Index Including Over-Modulation Region, with Neutral Point Balancing
Abstract >> Three-level neutral point clamped (NPC)
inverter is a widely used topology of
multilevel inverters. However, the neutral
point fluctuates for certain switching
states. At low modulation index, the fluctuations
can be compensated using redundant switching
states. But, at higher modulation index
and in overmodulation region, the neutral
point fluctuation deteriorates the performance
of the inverter.
This paper proposes a simple space vector
pulsewidth modulation scheme for operating
a three-level NPC inverter at higher modulation
indexes, including overmodulation region,
with neutral point balancing. Experimental
results are provided.
