First model example with PLECS
This page shows how to run your first example of a PLECS based OwnTech model.
Requirements
Before you start, please make sure you fullfil the requirements below.
Requirements
- Have installed and configured the licence of your PLECS instance
- Setup the OwnTech PLECS library.
Running the open loop model for the first time
We have developed a first model that you can run out-of-the-box. Here are the steps to launch it.
Step 1 - In PLECS Library Browser go to File->Open
Step 2 - Navigate to the Open loop folder. Choose the Twist_open_loop.plecs and click Open*.
Step 3 - You will see the model and a scope window. Press Ctrl+T on your computer or click on Simulation->Start.
Step 4 - The simulation will run its course and give you the results as in the image below.
You can see an initial in-rush current for loading the Twist board capacitors. At 1 milisecond, the Twist board starts to operate and voltage goes up to around half of the generator voltage, as expected for a 50% duty cycle setup.
Analyzing the model a little further
The open loop model will allow you to explore how the twist board operates.
The model input is a standard voltage source with an inductive impedence and a bus capacitor.
The output is a 1 Ohm resistor.
You are now able to run simulations. The next step is to run closed loop simulations using this model.
