DC/DC conversion lab in engineering curriculum

Hello,

Here is the assignment of the first lab session with CentralSupélec engineering students which just ran today!

The topic is DC/DC conversion and it is done with an OwnVerter board + inductive filter:

(in French)

The session was 3 hours long. We didn’t cover the full assignment, only the beginning:

  1. Getting started with OwnTech board (programming with VSCode/PlatformIO): ~1 hour
  2. DC/DC conversion experiments in permanent regime: parametric study (effect of L, duty cycle, Vhigh): core of the student work. This include a quick comparison with a Simulink/Simscape circuit model
  3. Transients: in the last 15 minutes, the students manage to capture one duty cycle transient (i.e. exponential transient for the average current)

What was left out:

  • average circuit model (also with Simscape), transfer function model
  • voltage regulation with a PI controller (beyond the time issue, they haven’t had the PI control lecture yet…)
