Active learning in high engineering school is a real opportunity for students. Indeed, it enables to discover some subject deeper than a traditional lectures classroom. In this paper a project example, mainly based on power electronics, has been described. This project has taken place in a non-specialized French engineer school with the financial partnership of Renault. Each actor gives its advice at the end of the project (student, professor and industrial partner) about the learning process in power electronics but also about the global project activity.
