Yes the transformer is have extra leakage inductance to achieve ZVS not a shim inductor. That might be the reason that I don't see the flux walking.FET resistance is 60mOhms.It is high cause voltage rating is at 650V.May be the both effects are combined and make the flux walking vanished.Thank you for your informative reply
