How to resolve this error: Derivate is infinite or NaN

2,304 views

Hi

While running my simulation I get the following error at about 0.1 simulation time. This started occurring when i changed the PI parameters for a voltage controller for inverter which is connected in parallel to PV buck-boost converter.

Attached figure shows the schematic with PV , TPFC(totem pole power factor correction) and Dual active bridge.

I have tried chnageing tolerances, varying step size, changing solvers. I do not want to revert back with the PI parameters of inverter. Is there anyway this can be solved?

Since there are multiple diagnostic messages shown, you should share the model to get support.
