Can't claim practical experience, but I did run a Spice simulation. I
assumed the primary R effect doubled the secondary Rs, and I assumed about
4.5kV dc (didn't keep a copy of your original post).
At .75A dc in the load, the current in the diodes is 6.5A peak. At 2A dc,
the diode current is 12A peak, with a longer conduction period. This is 40ms
after 'turn on', when the current appears to have settled to a constant
value.
