Hello,
Here is two identical Full Bridge SMPS simulations in the free LTspice one has leakage inductance in the transformer, the other has perfect coupling (no leakage inductance).
Notice how the one with leakage inductance has far less severe reverse recovery of the secondary diode. (attached are waveforms of secondary diode voltage (green) and current (red).
I believe that leakage inductance in a Full Bridge SMPS is in fact advantageous to an extent, and there is no need to do “interleave winding” to reduce Leakage inductance in a Full Bridge SMPS transformer. Do you agree?
Also attached is the full bridge schem and the ltspice simulations.
