Architecture en Couches: Exemple

This document elaborates on structuring software projects by leveraging layered architecture principles. It introduces a simplistic example of a calculator project, highlighting separation concerns between the user interface (IHM) and the core functionality (business logic). Critiques emphasize the necessity of modularity and the adoption of design models such as MVC (Model-View-Controller). The document provides a comparative analysis between monolithic and multi-layered designs, advocating for the division into reusable components to improve maintainability and scalability.

TD 3: Les Convertisseurs DC/DC

This document presents three exercises focusing on DC/DC converters (buck and boost types). The first exercise analyzes the operation of a buck converter feeding a DC motor, covering voltage and current waveforms, as well as expressions for current ripple. The second exercise delves into a buck converter with a constant flux DC machine, deriving current expressions, ripple, and waveform characteristics. The third exercise discusses a boost converter and calculates voltage gain, current ripple, and dynamic parameters for specified operation conditions. Each exercise focuses on extracting ana...
