Simulation Tools and Thermal Applications in Conversion

In the design of energy conversion systems, in the context of a feasibility study for example, it is essential to use scientific computing software and/or simulation software which will allow substantial time savings.

This teaching unit will:

• To provide knowledge of numerical calculation methods used in commercial software used to solve problems applied to electrical engineering.
• Introduce optimization concepts for the search for an optimal solution under constraint in a problem related to electrical engineering.
• Enable the implementation and application of digital techniques for the processing of data from, for example, the reliability study of an electrical system or power electronics.
• Present the finite element methods and software used for the resolution of physical or multi-physics problems.
• Deal with thermal problems related to energy conversion and will provide theoretical knowledge necessary for the understanding and modeling of thermal phenomena in electrical engineering components and systems (power electronics, HF transformer, distribution cables, etc.).

At the end of the course and practical work, the student's final objective is to master the basic techniques encountered in computer-aided design (CAD) and in the use of CAD software for electrical engineering. This teaching unit will enable the student to join research and development offices or research laboratories, where he or she will work on the study and design of components and systems requiring the use of CAD software.

At the end of the course and practical work, the student :

• Will be able to use scientific software and implement numerical calculation, optimization and data processing techniques.
• Interpret software results and assess their relevance to the study.
• Assimilate the underlying operating and calculation principles of finite element software, enabling you to cope with any situation or adapt to new software.
• Independently define, model and solve a thermal problem applied to electrical engineering.
