Hi Bert,

The way I see it, the energy of the primary cap should go to primary coil,
not back to the secondary power supply! Performance is the ratio Pout/Pin.
'The bidirectional energy transfer' you are talking about is loss, so the
diode(s) should improve things in my opinion. Of course I have not so many
experience with TC's, so excuse me if I am totally wrong with this theory.
