Information
BoostConverter
Introduction
This model studies the switching behavior of a 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 BoostConverter.nb notebook that came in the same bundle as this model
These pages show an overview of the example. For the full example, open the accompanying notebook BoostConverter.nb.
Dynamics
This is a model of a boost DC-DC converter. The parameters are taken from an example in the WhenEvent Wolfram Language documentation.
Simulation
To simulate the model, perform this step:
- Click the Simulate button in the top toolbar
.
Energy Conservation
Explore how the target voltage is achieved in the converter at steady state by looking at the stored plot that is automatically displayed:
In the plot you can now see that the input voltage is lower than the output voltage.
System Behavior
You can study the behavior of the system closer to steady-state by clicking the Load Voltage at Steady State stored plot.
Parameters
Try chaning the c1 and l1 parameters in the Parameters tab. See how it affects the rise time of the system. Changing the V0 parameter will change the reference point for the output voltage by changing the duty-ratio of the switch.
