Authours suggested 25 level structure with all bidirectional switched with four sources. Following points may be considered for enhancement of the manuscript.
1. Please revisit references, there exist many other asymmetrical MLI structure with fewer numbers of device count. Please compare your structure with the latest literature. Do not keep an aim to show the best performance rather highlight the unique advantages of your MLI structure.
2. Studies were carried out considering R-L load which is dominantly resistive. Please check the performance of your configuration with an extreme case of pure L/C load. It should retain the level for such load also.
3. Cascaded connection simulation results may be added and analyzed.
4. Nothing is done on the control circuit side; what is the logic of showing dynamic performance in the results? It is the natural response of the system.
5. Hardware results are very primitive and similar to simulation results. Seems realtime simulation results displayed on DSO through analog out the channel.
6. The suggested configuration requires two pairs of identical sources V1 and 5 times V1. How to get it practically, it will not be practical? What will happen if there is a minute difference between the two V1 sources or two V2 sources?
7. Check typographic error and also check figures all figures. There are many mistakes.
