Round 1

Reviewer 1 Report

The paper is well-written and the topic is of interest to EV charging researchers. The paper addresses the problem of energy loss in soft-switching operation. Though the efficiency improvement percentage is small, the paper has reference value. I have a few minor comments for authors to consider:

- In Conclusions, please more quantitatively describe the adjustment needed to improve efficiency when soft-switching is implemented. In other words, please elaborate the proposed “guideline” in a few sentences in Conclusions.

- When describing efficiency improvement in results and conclusions, please also indicate the actual percentage improvement at certain power rate, e.g., X % improvement when output power is at X kW.

Reviewer 2 Report

In this paper, discussed has been the influence on the efficiency of the resonant circuit caused by the soft-switching operation in bidirectional  inductive power transfer systems with series - series transfer circuit, and the guideline for improving the efficiency of the systems is proposed. The paper is interesting and informative.

A control circuit diagram for the system in Fig.1 should be indicated, and especially, I suppose it is necessary to explain briefly how the phase difference between the converters is detected without wire in the actual system.
