Uči Ti, Uči Ti i samo Uči Ti...Lenji N...(1) 2-Section Wholly-WrappedPrimary winding:No. of Sections = 2No. of turn per section = 14 turnsStranded wire = 12 threads of AWG25Total Inductance = 3.5mH at 10kHz, Q = 46...Construction and Test Results:Primary windings were divided into 2sections, wound on the most inner and outer of thebobbin to enclose the secondary windingscompletely. Secondary windings were divided into4 sections wound inside the primary windings, andeach two sections were connected to form a centertab for output grounding.----However, the assembly procedures fortransformer no. 2 was much more complicated than thatfor transformer no. 1, so the simple 2-sectionwholly-wrapped technique was recommended, and theresults did also prove that the tighter the couplingbetween primary and secondary windings, the lower theleakage inductance, and the more stable the converterworks.
