Voltage Space Vector Equivalent Substitution Fault-Tolerance Control for Cascaded H-Bridge Multilevel Inverter with Current-Tracking

Round 1

Reviewer 1 Report

The reviewer does not consider her/himself as an expert on the field. S/He provides her/his opinion mostly based on rather generic knowledge on the field.

The manuscript entitled: “Voltage Space Vector Equivalent Substitution Fault-Tolerance Control for Cascaded H-Bridge Multilevel Inverter with Current-Tracking” describes a new method for H-bridge inverter with current-tracking voltage vector equivalent substitution fault-tolerant control. It well written and developed. Except from the theoretical analysis it provides the necessary experimental verification.

Bibliography is adequately recent and it is able to cover the subject, however, it is not clear to the reviewer the comparison on the existing work this research. The authors are invited to further elaborate and better explain the innovation of their methodology.

A flow chart for the voltage vector substitution strategy could improve this manuscript's readability.

Results show good consistency. Is it necessary to provide voltages for all three phases?

How much is the Total Harmonic Distortion before and after the fault? If it increases, could this be mitigated?

How the error of the experimental waveforms could be reduced?

Conclusions, to a certain degree, repeat the introduction. It is rather expected that the findings of the methodology are explained.

Having mentioned the above, this manuscript is proposed to be published after minor revision.

Paper review

Voltage Space Vector Equivalent Substitution Fault-Tolerance Control for Cascaded H-Bridge Multilevel Inverter with Current-Tracking

Authors:  Guohua Li, ChunwuLiu and Yufeng Wang

In this paper the authors propose a method to substitute the voltage space vector with current tracking, for controlling the multilevel cascaded H-bridge inverters.

The content of the paper is well documented in the introduction of the paper, the strategy of current tracking and the fault-tolerant control is clearly explained in the following chapters. The experimental results are in concordance to the explanations, but as a recommendation the set up for the experiments should be better explained, with a block diagram or a schematic, besides of the photo. It should be also required to emphasize more the advantages of the method and also the disadvantages compared to the voltage space vector equivalent in a detailed manner.

I think the paper is interesting for the readers with a novelty idea and I recommend it for acceptance after minor revisions.
