Hybrid Pulse Width Modulation Strategy of a High-Frequency Link Three-Phase Four-Leg Matrix Converter Based on Compensation Theory

Round 1

Reviewer 1 Report

1. Such topology will yield the high current ripple flowing through Udc. Please add the current flowing through Udc;

2. Since now the control of the three-phase four-leg part is coupled with S1~S4, some simulation waveform to show how you do phase-shift control is needed. 

3. Experimental validation is highly recommended.

Reviewer 2 Report

The paper proposes a Hardware Pulse Width Modulation for 4-wire matrix converter, which is based on the fourth bridge leg compensation method.

The paper is interesting and is in line with the aims and scope of the Journal: the problem faced in the described study is relevant for practical applications, therefore it can raise the interest of the readers. However, it requires some improvements in order to deserve publication.

The analysis of the state of the art, which is proposed in the introductory section, is clear and well developed, by correctly highlighting the added value of the proposed research.

The control strategy is well described and detailed. However, Figure 5 should be improved and made clearer, for instance, by using colored lines. Moreover, it should be depicted in deeper detail in the text.

The simulation study is well conducted and correctly explained. However the quality of the proposed figures need to be improved, as some of them are difficult to read.

Considering the intensive use of acronyms and symbols, which is done throughout the whole paper, the paper should contain a list of symbols and acronyms.

In general, the English language is quite poor and need to be revised in order to make the paper suitable for publication.

Minor remarks:

the use of acronyms should be avoided in both the title and the abstract; please avoid referring at cited literature results with expressions like “in Reference [X]”; the authors can use instead the number only or the names of the authors of the cited publications; page 7, rows 230-231: this sentence is unclear; the first word of a sentence cannot be abbreviated.

Reviewer 2 Report

The paper proposes a Hybrid Pulse Width Modulation for 4-wire matrix converter, which is based on the fourth bridge leg compensation method.

The paper is interesting and is in line with the aims and scope of the Journal: the problem faced in the described study is relevant for practical applications, therefore it can raise the interest of the readers.

The authors improved the paper according to the provided suggestions and such reworking greately contributed to overcome the weaknesses and drawbacks.

In my opinion the paper is now suitable for publication.
