Homework Statement
Hi everyone,
I am now studying the Flyback converter as a component in a SMPS,
my question is on the transformer unit on the converter.
There are Primary side and Secondary side in the converter,
at any given moment only either of the sides conducts, that is, when Primary conducts, Secondary doesn't.
From the book I am reading now, on switching to the OFF state, huge spike can arise as a result of the leakage inductance.
Does it mean, if we assume perfect coupling and neglect the effect of leakage inductance, we can actually strictly cut the current in the primary side from a finite value to zero without causing a spike, as the energy is free-wheeled via the secondary circuit?
Thank you.
