Reviewer 1 Report
The paper presents a novel topology for supplying the high power necessary for wireless charging of electric vehicles, one that is meant to avoid high-frequency switching losses. Experimental results are confirming the theoretical approach, resulting in a system with a power transmission efficiency of 94.1%.
The studied literature consists in a number of 28 references, all relevant to the topics of wireless power transfer, electric vehicles and control methods for EV battery charging.
The as stated before, the proposed topology is mathematically modeled, simulated and experimentally implemented, proving the effectiveness of the controller.
There are very few errors in the manuscript that have been highlighted in the attached file, nothing that couldn't be very easily corrected.

Reviewer 2 Report
This paper introuduces the parallel modular multi-Inverters uesd for the wireless charge. The paper is well writen, and it has great potential applications. There are some minor factors they author need to consider:
1. On page 1, line 30, what is "high-frequency"? Can you author add a specific number to define it?
2. In Fig. 8(b), can the author add different shapes to the two curves? It is black-white print friendly.
3. Could you list a table to compare the advntage and disadvantage of the method used in the paper and other popular methods?
4. Could you discuss the disadvtange of this method?

Reviewer 3 Report
This manuscript presents a control method to achieve ZVS in a
power inverters connected in parallel to a WPT. The work is well organized and the idea is clearly presented. Although some analyses such as efficiency considering ZVS and phase, and the control behavior taking into account the energy transfer effects such as dealignment, load variation, and distance could improve this work.
What happens if the load R range is larger?
What is the control performance considering the secondary-side effect?
What is the limit to connecting the inverter with the same control system?
It is possible to have a ZCS with a similar method?
