A survey on capacitor voltage control in neutral-point-clamped multilevel converters
(MDPI, 2022-02-10)
Neutral-point-clamped multilevel converters are currently a suitable solution for a wide range of applications. It is well known that the capacitor voltage balance is a major issue for this topology. ...
Fast reliability assessment of neutral-point-clamped topologies through Markov models
(Institute of Electrical and Electronics Engineers (IEEE), 2021-06-08)
This article presents detailed Markov models for the reliability assessment of multilevel neutral-point-clamped (NPC) converter leg topologies, incorporating their inherent fault-tolerance under ...
