Proof of Concept - A breadboard was constructed, of readily available parts, according to the TinyCad schematic:

 

 

 

                                 

Construction -  The two transformers are wound on toroidal cores.  A photograph:

 

 

Function Test - Power was passed, between the ports, in both directions, while monitoring waveforms on an oscilloscope.  Everything worked as intended.

 

Conclusions - The concept is valid.  Construction of more refined models, and efficiency measurements on them, is warranted.
