Hi,
Doing an LLC transformer on E70. 400vin, +/-180vout, 4Kw, 100kHz
Sec is split
Primary is in 2 series “halves” which “sandwich” the 2 secondaries.
Np1-Ns1-Ns2-Np2
Its 9-8-8-8
E70 former is 40.9mm wide.
Problem is , I only have 7/0.3mm TEX-ELZ, that cost over £100, so I cant buy any more different sizes….all windings must use this.
The primary is 3 strands. Sec’s are 4 strands. The first primary layer is only 32mm width’s worth of windings…..so its gappy as the winding length is 40.9mm. Ditto the second primary layer…..i will just have to space them as evenly as possible.
Do you think this will affect the leakage inductance very much? (leakage seen at pri with both secs shorted)
