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.
