Compensation of Voltage Sags and Swells Using Dynamic Voltage Restorer Based on Bi-Directional H-Bridge AC/AC Converter

Round 1

Reviewer 1 Report

Already few papers are available to mitigate Voltage sag and swell using H bridge, But author did not mention those references.

What is the advantage of DVR instead of using Direct H bridge connection.

Size of the Capacitor and Inductor.

Size of the system.

Advantage of current DVR system.

Did not understand Efficiency Vs output power in terms of Voltage. Need more explanation.

Reviewer 2 Report

This paper has presented a methodology for compensating voltage sags/swell Bi-directional H-bridge AC/AC Converter. Although the paper is well written it needs further modifications to publish in this journal.
Comments to Authors:
(i) Include a clear research gap and new contribution in Introduction based on recent literature on the proposed topic.
(ii) Provide a flow chart/step by step method to show how the controller is designed and gain is selected
(iii) Compare the result with that of a similar design and topology to show the efficacy of your proposed system.
(iv) Show a comparison of simulation and experimental results in terms of percentage of error? Was the same system used in both simulation and experiment?
(v) Discuss the findings from the analyses and critically analyze the results
