Charles,

How can you say that body diode conduction will be reduced in 3-level modulation as compared to 2-level modulation?

Agree! Diode conduction problem depends on output topology, not modulation method.

The whole was depending on a single-ended three level output stage and the preferred way I would have implemented it would give some relief regarding reverse-recovery.

Charles,
What would be that preferred way, just like the autoformer [referring to your cross-conduction reduction technique thread]at switching node?

No it would have been a "real" three-level output stage.
