Reviewer 2 Report
Dear colleagues, your article has good quality and experimental results. I have a few suggestions, Please Improve Fig. 1. It seems the dc-dc converters may be in the wrong connection. Please include a loss breakdown of devices. The only disadvantage in the topology is that the battery is connected in parallel to a capacitor which current is discontinuous, this may increase the RMS value of the current and produce additional losses, please include some comments regarding this issue.
Another think I have to tell you is: The English grammar needs a good revision. The article has many typos and sentences which can be improved. I have included some particular suggestions. The English revision is not exhaustive, but I suggest an exhaustive revision.
On page 1, line 1, it says:
“A two switchs nonisolated DC-DC three port converter”
- I suggest changing it for:
“A two switch nonisolated DC-DC three-port converter”
On page 1, line 3, it says:
“The proposed TPC is integated with one low voltage input and one high voltag port which is suitable for photovoltaic (PV) application”
- I suggest changing it for:
“The proposed TPC is integrated with one low-voltage input and one high-voltage port, which is suitable for photovoltaic (PV) applications”
On page 1, line 5, it says:
“In addition benefiting from a modified SEPIC circuit, fewer number of componets are employed”
- I suggest changing it for:
“In addition, benefiting from a modified SEPIC circuit, fewer components are employed”
On page 1, line 6, it says:
“Further, state space method is adopted to analyze this multiple input multiple output (MIMO) system, and then small signal model is built to design an appropriate control strategy”
- I suggest changing it for:
“Further, the state space method is adopted to analyze this multiple inputs multiple outputs (MIMO) system, and then a small signal model is built to design an appropriate control strategy”
On page 1, line 8, it says:
“Finally proposed 100W TPC connects solar PV, energy storage to load with the effiency from 85% to 94%”
- I suggest changing it for:
“Finally, the proposed 100W TPC connects a solar PV energy storage to load with efficiency from 85% to 94%”
On page 1, line 8, it says:
“besides steady and dynamic state performances of this TPC is verified in SimStar MT3200 HIL platform, which illustrate the feasibility of proposed TPC and its power control strtegy for solar PV application.”
- I suggest changing it for:
“Besides, the steady and dynamic state performances of this TPC were verified in the SimStar MT3200 HIL platform, which illustrates the feasibility of the proposed TPC and its power control strategy for solar PV applications.”
On page 1, line 25, it says:
“However this type brings about verious drawbacks”
- I suggest changing it for:
““However, this type brings about verious drawbacks”
On page 1, line 25, it says:
“in this reason these two aspects high voltage gain and low volume seem contradictory which is worth considering and solving.”
- I suggest changing it for:
“For this reason, these two aspects, high voltage gain and low volume, seem contradictory, and it is worth considering and solving this tradeoff.”
