A Three-Coil Constant Output Wireless Power Transfer System Based on Parity–Time Symmetry Theory
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsIn this study, authors has been analyzed Three-coil PT-WPT system based on circuit theory which derives the transmission efficiency, output power, and transmission gain of the system and compared with the two-coil PT-WPT system. Authors are advised to make the following corrections.
-Reference indications in the literature review should be placed at the end of the sentence.
-Also, references throughout the article are not listed properly.
-There is no explanation in Headings 2.2.1 and 2.2.2. It should be added.
-Heading 3.2 and 3.3 are the same, should be checked.
-Fig.8(b) is not understood, it should be made more understandable.
-Line 399 should be checked, (decreased?> increased)

Reviewer 2 Report
Comments and Suggestions for AuthorsComments to the authors:
1. The authors are recommended to provide a related work sub-section, and show more clearly the main difference/main advantages of this paper as compared with the related works
2. Main contribution of this paper should be highlighted in Introduction Section
3. The authors should present more clearly the new points in the proposed model given in Figure 1 in this paper.
4. Some equations in this paper should cited to the original sources
5. Contents and figures that are re-used from the previous works should be cited appropriately
6. Some figures in this paper are over the margin
7. Figure 6 is not too clear to read in the printed PDF file
8. There are many other errors in this paper, for example
- PT-WPT should be written full name in the abstract
- “in 2007[5]” should be corrected by “m in 2007 [5]”
- “theory.[9]” should be corrected by “y theory [9].”
- “[20-22] realizes” should be corrected by “Published works [20-22] realize”
- “Based on the analysis of II-B”: The Reviewer cannot find the section II-B in this paper
- “Figure. 12” should be corrected by “Figure 12”. Please correct all the similar typos in this paper.

Reviewer 3 Report
Comments and Suggestions for AuthorsA three coil WPT has been proposed to provide a constant output and validated with an experiment. The paper is well organized and explained in a detail. The followings can be considered in the revised paper.
1. In (4), the region for the \omega can be overlapped. How can the \omega be chosen for two overlapped region?
2. Equations (5) – (8) are somewhat important. Maybe, the simple derivation procedure is provided.
3. The compensable range of the resistance (\delta R) can be provided?

Reviewer 4 Report
Comments and Suggestions for Authors- The introduction needs to clarify that wireless power transfer system based on Parity-Time Symmetry Theory has been researched? So, has this research problem been resolved?
- Adding research method section.
- Figure 6 needs to be enlarged.
- In the introduction, the author wrote "This method requires current and voltage information at the transmitting end of the system without communication at the receiving end". Therefore, do the simulation and experimental results represent the voltage and current results of the wireless power transfer system?
- In section 4.3.5. Comparison with other WPT systems, need to specifically add reference documents used for comparison, and which technical parameters to compare with each other (table can be used to demonstrate).
Comments on the Quality of English LanguageEnglish needs to be improved.
