Leakage inductance measured at one primary "half" was 100nH....this was with all three secondary wires shorted together. As such, do you agree, the leakage is 50nH in primary "half" 1; 50nH in primary "half" 2; 200nH in secondary "half" 1; 200nH in secondary "half" 2.

You mean short one pri half and measure the inductance of the other? Upvote 0 Downvote
