I am designing a halfbridge LLC converter. Due to different reasons I want to use transformer leakage as resonant indu ctor. As production are concerned, what are the best way to achieve the tightest results? I have made some experiments, with a 2-sectioned bobbin, but as soon as the transformer are wound, it's no way of "trimming" or adjusting the leakage. I then made a new transformer on one section, where I simply adjusted the l eakage to my specification by winding the primary on the left side of the b obbin, and the secondary on the right side. Then I moved a few turns of the secondary on top of the primary, until the leakage was spot on. Will this add any drawbacks to the design?
Best regards PAF
