Teaching methods

Lectures with Power Point slides.

Numerical simulation with MATLAB.

Lab test with DC/DC converters.

Assessment methods

Locally developed pre- and post- tests will be used to assess skills in power converters analysis and design.

Teamwork projects will be used to assess the capability of solving real problems, e.g. basic power stages for wind and photovoltaic converters.

All students will show substantial improvement in stated learning outcomes, as indicated by pre- and post- evaluation of real problems.

The final test will be a oral examination. Pre- and post-evaluation are mandatory conditions for the final test.

Teaching tools

Lectures with Power Point.

Teamwork and numerical simulation of basic power converter topologies.

Design kit of DC/DC power converters.
