Why is it important?
The neutral-point potential balancing control is essential to the application of NPC inverters for power electronic converters in high voltage DC power transmission, photovoltaic grid-connected system and high power flexible alternating current transmission systems using voltage source converters
Perspectives
The three-phase SHEPWM line-to-line voltages of the inverter are considered as switching-states. This new idea is then used to balance neutral-point potential.
