Bidirectional Six-Pack SiC Boost–Buck Converter Using Droop Control in DC Nano-Grid
Round 1
Reviewer 1 Report
This paper proposes a bi-directional boost-buck converter employed 6-pack SiC using droop control in DC nano-grids. It is interesting and has practical significance.
1) The figure 3 part should be placed in the introduction part.
2) The simulated waveforms from charging battery to discharging battery, and from discharging battery to charging battery should be added.

Reviewer 3 Report
This paper proposed a Bi-directional Boost-Buck Converter with Droop Control. However, the reviewer has some questions.
1. Please talk more for the background of the importance of the bidirectional converter for DC microgrid. E.g., the application of bidirectional multi-port dcdc converter for DC microgrid. Paper “Adaptive Bidirectional Droop Control for Electric Vehicles Parking Lot with Vehicle-to-Grid Service in Microgrid” could be a good reference.
2. For the review of the bidirectional DC-DC converter, dual active bridge based is also a typical topology. Please demonstrate why dual active bridge is not selected as your topology. Paper “Model Predictive control of dual-active-bridge based fast battery charger for plug-in hybrid electric vehicle in the future grid” can be a good reference.
3. For the proposed topology, the similar topology has already existed. Could you please justify the novelty of the proposed topology?
4. With the proposed topology, the different switch needs to stand for different voltage stress or power stress, which is important to the reliable operation of the power converter. Could you please demonstrate more about the voltage or power stress analysis?
5. Author claims that the maximum efficiency is 99.2%, however, without the soft switch technology, how does it realize?
6. Could you please have a table to list all the parameters of the prototype?
