|---|---|---|
Multilevel converters have been well studied for high-voltage high-power renewable energy applications. Owing to the multibranch structure, these converters can be operated under fault conditions in case of a loss of a branch or voltage cell. In this regard, this paper proposes a new active fault-tolerant space vector pulsewidth modulation strategy for single-phase faults in three-phase multilevel converters. The proposed modulation strategy treats the multilevel converter as a two-level converter by introducing an offset vector. A generalized approach is proposed to search for the offset vector and to adjust the modulation of the converter online under different fault operation conditions. Several short- and open-circuit faults have been demonstrated on a seven-level hybrid input-switched converter to prove the effectiveness of the proposed fault-tolerant scheme. |
