Hi Danikha,
I understand that you are facing issues in implementing automatic switching based on the input voltage to power up a three-input buck-boost converter. To achieve this, you would first need to invoke the if-else conditions in your model.
You can utilize a switch block in your model to invoke the if-else conditions. Since your logic requires many conditions, you can use multiple switch blocks in series to implement the logic.
Refer to the image below for the implementation.
Edit: The above mentioned method could create hassle when there is a large number of inputs. It is better to use the variant source block to achieve the same. The documentation for the variant source block is available at the link below:
I hope this addresses your query.
Best Regards
Yash
