Hello,
I am currently working on a simulation for a bidirectional flyback circuit (output diode replaced by a NMOS). When I am using generic components, everything works fine. However when I use
manufacturer supplied spice models for the MOSFETs, I keep getting unwanted oscillations while the mutual inductor is charged (current ramping up).
I assume the oscillations come from the LC tank consisting of the transformer primary inductance and the MOSFET parasitic capacitance. Could this be a simulation problem? I attached the waveform of the transformer primary current showing the oscillations.
Thanks for any help!
