Tool/software:
Hi Team,
I was checking the PSFB interleaving simulation by constructing 2 number of 6.6 kW models as per the attached pdf and configuring them in master slave.
Issue description –
- Slave inductor current becoming unstable with subharmonic oscillations.
- Before first occurrence of slave inductor current getting unstable (at 2.5milliseconds), the slave OUTA is leading the master OUTA, which seems incorrect as per the datasheet. While after becoming stable (at 4.2 milliseconds) the master OUTA is leading slave OUTA, which is following the mentioned signals in the datasheet.
- Tried the simulation with lower output voltage 14V to get lower duty than 0.5, still the subharmonic oscillation of slave did not resolve.
