Minimization of the Decoupling Circuit (DC-Link) in Induction Motors

Round 1

Reviewer 1 Report

The paper titled “Minimization of the decoupling circuit (DC-link) in induction motors”; is reviewed.

1. First, I would like to congratulate the authors for writing the paper in more appropriate manner.

2. Introduction section is so nicely written, and a small suggestion is to incorporate the references more of recent five years.

3. somewhere in text (see Fig. 1). Is quoted and somewhere Figure…maintain as per journal requirement.

4. Figure 7 is not cited in text.

5. Merge the results and discussion heading in one and summarize it accordingly.

Reviewer 2 Report

1. It is recommended that the section: 2.2 Analysis and mathematical development, should be renamed as: Development of mathematical model or equation, as this section is the main contribution of the paper.

2. Need references for the section 2.2. 

3. The novelty of the paper should be explained explicitly in the Introduction part. 

4. Some of the data presented in the tabular form (Table 6 and 7) can be presented in a graphical form. 

5. More recent references that focus on stability and reliability aspects of DC link or battery or EV performance will be a good addition. The paper should include such papers in literature: For instance,

Reviewer 3 Report

Decoupling capacitor is a capacitor used to decouple (i.e. prevent electrical energy from transferring to) one part of a circuit from another. Noise caused by other circuit elements is shunted through the capacitor, reducing its effect on the rest of the circuit. For higher frequencies, an alternative name is bypass capacitor as it is used to bypass the power supply or other high-impedance component of a circuit.

The hypothies of the work is not clear. It is indeed for any research article. Kinldy improve the introduction.

1. Many figs are taken from published work. I donot know , is the copy rights permission has taken. 

In general , it is not a good practice to take picture directly the published documents - Please do the won diagram ( Fig.2) 

2. not in the format - Table 1. Motor specifications

3. All Fig . 3 to 6 is not clear 

4. How the design Design specifications used for the analysis is taken. 

5. results are not convinced

6. Matematical model of Decoupling capacitor is not discussed 

7. Figure 11. Schematic system diagram - remove the MATLAB simulation Digram 

8. Paper is very weak. Paper is not concluded properly.

Paper has to rewrite completely

Round 2

Reviewer 3 Report

1. Case study selection  - still needs improvement 

2. Conclusion to be revised 

3. Please go through the one again the introduction 

4. Please remove unwanted references.
