Buck-Boost Converter

Introduction

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:

• A desktop Wolfram Language product; a free trial download is available at www.wolfram.com/mathematica/trial/
• The BuckBoostConverter.nb notebook that came in the same bundle as this model

Dynamics

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.

Simulation

To simulate the model, perform this step:

• Click the Simulate button in the top toolbar .

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:
