WOLFRAM SYSTEM MODELER
Model of a DC/DC Buck Boost Converter used to study rise time and output current ripple.
|ˇ Introduction||ˇ Dynamics|
This model studies the switching behavior of a buck-boost converter.
In order to get the full experience of this example, you need the following:
These pages show an overview of the example. For the full example, open the accompanying notebook BuckBoostConverter.nb.
This is a model of a buck-boost DC-DC converter. The parameters are taken from an example in the WhenEvent Wolfram Language documentation, with a larger capacitor. It can be found in the Applications section under Power Electronics.
To simulate the model, perform this step:
A stored plot will display automatically. The plot window should now look like this:
You can change the Vin and Vout parameters to try different input and output voltages.
You can also zoom in to see the output ripple:
