Hi Alfred,
Interesting. Can you elaborate on a few points please?

What secondary parameters were changed in order to change Fr? Which
primary values? Running at a higher frequency but keeping throughput
and output voltage the same implies that primary capacitance, voltage
and breaks were the same, and secondary size (capacitance) and
terminal were the same (which leaves only inductance variations).
Thanks,
