Phase shift bridge simulation in Speedfit

I'm having trouble running a simulation for phase shift full bridge in Speedfit.


Using ideal diode and heatsink, simulation won't converge using below conditions:

Error message suggests inductances are too large however Speedfit doesn't allow user to change Cr and Lr manually.

Changing frequency from 80kHz with according Cr&Lr allows the simulation to run, however output power is limited to 10.95kW

Can someone look into this and let me know why Cr/Lr can't be changed manually, and why output power is capped?


Thanks!
