A Space Virtual-Vector Modulation With Voltage Balance Control for Nested Neutral-Point Clamped Converter Under Low Output Frequency Conditions
Abstract
The recently-developed nested neutral-point clamped (NNPC) converter is a four-level converter for medium-voltage high-power applications. It has some merits such as operating over wide voltage ranges (2.4-7.2 kV) without switching devices in series and less diodes or capacitors when compared with classical four-level topologies. But it has severe voltage balancing problems under low output frequency conditions when conventional space vector …
