[QUOTE="Mars, post: 80270, member: 817"] I have downloaded Yve's latest OPT da from the link he kindly gave above, and updated my data files. Let's recap: We want the: Leakage L < 8mH Primary inductance > 100H Total Cu losses < 10% Total Flux (B total) < 1.1 Tesla .........(laminations are Non Grain orientated) Power 16.5 Watts Bandwidth 30Hz to 100kHz (?) Layering arrangement 2 Primary sections interleaved with 2 Secondary sections Secondary limited to a single layer filling the whole bobbin width Using EI96 laminations stacked 32mm high I also took note that the current (Ip0) should be halved. [IMG]http://farm2.static.flickr.com/1061/5168725662_4ab696d1ae_b.jpg[/IMG] We come close to our target: Leakage = 12.1mH Cu losses < 10% Primary inductance = 92.9H B Total = 1.09 Could this be the the one? There is still a bit of room to fill in the window: Only 8.5mm of the available 14mm height of the bobbin is filled. Real world winding typically exceeds the predicted height, so lets come back to that later. [/QUOTE]
