Hi,
We will use PH9572.111 with the secs in p'llel, since its only a Two tran forward. (just drive bottom fet directly) Do you think the pri is sandwiched inside the 2 secs?

Hi,

Option 1: Ask the manufactuer. I was already in contact with PULSE, they are quite responsive, at least with my company mail address .
Option 2: Buy one and rip it appart.

There will be circulating current losses with mismatched secondaries in parallel.

There will be circulating current losses with mismatched secondaries in parallel.

What is "mismatched secondaries"?
- Unequal winding ratio. Can be considered as manufacturing defect.
- Unequal leakage inductance. Expectable, causes unequal current sharing but no additional losses.
