Hello,
I’ve been working on a PSFB converter for a while. Plecs simulation is great but it doesnt work in applicaiton somehow. There is a problem in transformer I guess , so here is the scope waveforms for primary voltage and current of transformer.
It is pretty weird because when primary voltage is high to input voltage , it is supposed to be power transfer(except loss time caused by slope of the primary current) and current needs to supply the load thus it should remains relatively constant for a power transfer interval. Is this something about magnetizing current or primary inductance ?
