Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

2.5.1 Lecture: Power Electronics in Electric Cars

Course subject(s) Module 2. Battery Technology for EVs

When power flows from the battery to the electric motor, its voltage needs to be stepped up. How can this be achieved? You will find this out as Prof. Bauer explains the working of the boost converter and then combines the buck and the boost converters in a bi-directional converter for electric vehicles.

Learning goals for this lecture are:

        1. Explain the application of a boost converter in context of electric vehicles.
        2. Understand how a boost converter works.
        3. Explain the operating states of a boost converter.
        4. Derive the relationship between the input voltage and output voltage of a DC to DC boost converter in terms of duty cycle.
        5. Explain the working principle of a combination of the buck and boost converters?
