PowerSupply

 

Introduction

This model shows how to use a model for both reliability analysis and dynamic behavior analysis.

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 UPS.nb.

 

System Architecture

The system will use the utility power when available. The utility power will be transmitted through the lines component. The charger detects loss of power and triggers the battery to provide power. When the battery provides power (DC), it will go through an inverter that will convert the power into AC. Finally, the load is connected to both the lines and inverter.

 

Further Analysis

In the accompanying notebook, the switching behavior is studied. The reliability for the system is also computed.
