A Multilevel Converter Topology With Fault-Tolerant Ability
Abstract
A new topology with fault-tolerant ability that improves the reliability of multilevel converters is proposed. This new topology is developed through analysis of different power device's failure modes. With the proposed scheme, the function of the power stage can be maintained even part of it fails. Its fault-tolerant ability results from the redundant nature of the multiswitching-state topology and from control signal modification. Furthermore, it balances the voltage levels automatically without any assistance from other circuits. The validity of the proposed scheme is confirmed by experiments in a five-level single-phase inverter prototype.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
