Error in PV Array with a converter dc-dc Simulink

8 views (last 30 days)
Dear colleagues,
I have an error when I simulate the following design
I dont know why exists this error. The powergui is "Continuous" but with discrete I obtain the same error. Howerver if I put a capacitor in parallel with the PV array, the error doesn't appear. But I dont want to use a capacitor, I need to know what is the problem and how to solve it (I'm a little bit rookie with Simulink).
I would be very pleasant if you could help me.
Thank you in advance

If possible, I would share your model. I'd also try putting a resistor or a capacitor on the output of the solar panel. Something about the circuit is creating a system that the solver can't simulate but it's hard to pinpoint wihtout the full model.
