Adaptive Talkative Power in High-Frequency Bidirectional Boost Converters

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

1. In the Background section, the literature review is broad but lacks depth. The authors are encouraged to focus more on the core challenges addressed in the manuscript, rather than discussing literature with weak relevance to the major topic. Additional literature on adaptive data transmission, data reception, and efficient power transmission should be incorporated into the Introduction section to better show the contribution of this work.
2. Why does the switching device Q2 not include parasitic capacitance similar to Q1? The corresponding figure should also be improved for better clarity and accuracy. In the switching frequency adjustment section, why is the efficiency of the magnetic components of the converter not considered?
3. Please comment on the computation requirements of the proposed data reception method. It may be a challenge for typical MCUs or DSPs to be implemented with the learning-based approach in practical systems.
4. The switching frequency of the converter changes due to the proposed efficiency optimization method, so is the proposed data reception method still valid under varying switching frequency conditions?

Review of article:

Adaptive Talkative Power in High frequency Bidirectional Boost Converters

 

The authors present the talkative power framework, implemented on the bidirectional boost converter, operating in quasi resonant mode, in order to achieve soft-switching. Communication is achieved using Frequency  Shift Keying modulation, by warrying switching frequency, which results in changes in output voltage ripple. The changes in ripple are interpreted using a neural network. The proposed method was verified using HIL simulation.

 

The reviewer has following suggestions:

• Under Chapter 2, when describing the operation of the converter, authors could include switching waveforms, with marked intervals t_df, t_sr, t_dn, etc. This would better showcase the operation and ZVS properties of the converter.

 

• Equation (8) includes the value Req, which was not explained under the equation.

 

• The control block diagram in Fig. 3 has blocks denoted Gci and Gcv, which should be explained in the text. Transfer functions should also be included in the manuscript.

 

• Equation (9) includes input and output currents, which are not mentioned in the text and could also be marked in Fig.2.

 

• Authors should also include a const function, used for the optimization of the converter switching frequency (12).

 

• Description of factor m should be included before Chapter 4, as it is included in Table 1 and in Fig. 6.

 

• Authors should include a more precise structure for the NN. Is there a criterion that determines the size and structure of the network?

 

• The experiment was performed using real-time HIL simulations. How would NN be implemented on the physical converter, and how would it impact the performance of the system? What could be the challenges?

 

• What is the bandwidth of the proposed communication scheme?

 

• Is it possible to achieve bidirectional communication? The current setup communicates only through the changes in the ripple of V_out.
