The session will briefly review onsemi SPICE modeling state of the art. Then, the various switching transitions for a power conversion application will be detailed. We will analyze step by step current and voltage for a switching device during the various transitions. A transition between on-state to off-state or vice-versa can be Hard, Soft or a combination of Soft and Hard. Some basic topologies’ switching transition will also be described. We will conclude and create table that shows how the 6 transitions can be organized depending on the current flow for the turn-on and turn-off.
