Goal(s)

• Heat exchangers:
  This course covers heat exchangers. The objective is to specify the basic concepts which make it possible to calculate and size energy systems for the production/conversion of energy, but also to identify the limits of their possible optimization.

• Transformers:
  This teaching concerns electrical devices such as power transformers. The objective is to understand how the object works, know how to model it and insert it into the resolution of electrotechnical problems.

• Electronic power converters:
  Understand the need for power electronics, or static conversion. After describing the components constituting the power electronics systems, the basic architectures will be presented and analyzed. Their choices and sizing will be exposed, as well as their control laws.
