Hi Plecs Team,
I am working on PFC 2 level rectifier simulation in PLECS
But i am facing issue with operations and waveforms,attached image fyr
when i implement at Matlab it works fine
Let me know the issue please,attached PLECS file also

It seems your controls are not stable and one can see very early on the modulation index input exceeds the carrier signal.
I’d suggest debugging the circuit logically - first the modulator without current controls and a fixed DC output voltage, then the current controller with a fixed DC output voltage, then the outer DC current loop.
If you have a working model in MATLAB then one can study each system and determine where the translation error occurred.
