Authors have nicely presented novel topology. I have following concerns:
1) In depth detail of modulation method should be provided.
2) Topology parameters may be in terms of THD for better clarity.
3) Asymmetrical topology have any difference in power losses of switches? how it can be implemented on same heat sink? clear explanation should be stated
4) major concern is regarding short circuit with given topology. When p2 is on, source v1 get short circuited via two series diodes of b1. Similarly, when s3 is one, source v2 get short circuited via two series diodes of b2. Serious question is that, how simulation and experiments are performed in this situations?
5) more literature review is required.

Authors have addressed all my concerns positively.
