Two-level operation of a diode-clamped multilevel inverter

Adam, Grain Philip and Finney, Stephen and Williams, Barry (2010) Two-level operation of a diode-clamped multilevel inverter. In: Proceedings of the 2010 IEEE International Symposium on Industrial Electronics (ISIE). IEEE, 1137 - 1142. ISBN 978-1-4244-6390-9

This paper presents space vector based quasi two-level operation of a diode-clamped multilevel inverter in an attempt to improve the dc link utilization and output voltage quality, and avoids dc link capacitor voltage balancing problems experienced with standard multilevel operation. Beside a review of quasi two-level operation and a capacitor voltage balancing method, the paper presents a detailed discussion on space vector modulation implementation and selection of the switching sequence for the five-level inverter case. Additionally, the condition for maximum theoretical modulation index for space vector modulation is established. A prototype five-level diode clamped inverter is used to experimental validated the approach.
