Fortgeschrittene leistungselektronische Systeme - Entwurf und Implementierung eines DC-DC-Wandlers

What it is about

In this project-based module you develop a DC-DC converter from the specification to the tested lab prototype. In the end you will master electrical, thermal and magnetic design, PCB design, selection of power semiconductors and passive components, as well as the construction and measurement techniques for testing and evaluating a real power converter.

What you will be able to do

• Understand and carry out the entire development process of electronic hardware
• Specify and realize power circuits
• Evaluate active, passive and parasitic components
• Electrical and thermal design of power conversion systems
• Design of EMC filters and auxiliary circuits (e.g. gate driver, measurement circuits)
• Design of magnetic components (inductors, RF transformers)
• Calculation of losses and cooling load
• PCB design for power applications
• Laboratory practical skills: measuring (currents, voltages, power), soldering, winding, troubleshooting
• Project management for the development of a power converter
• Prototype construction, testing and analysis of measurement results
• Safe operating practices during tests of electrical devices

What the module consists of

• LectureExplanation of development steps, presentation of topics and discussion (2 SWS, 30 h contact time)
• Supervised self-study / LaboratoryPractical supervision and execution of the project work in groups (2 SWS, 30 h supervision)
• Independent studyPreparation and follow-up, processing of project tasks, creation of presentations and final report (90 h)

Teaching method

• Project work in small groupsTo enable practically oriented development of a power converter; promotes creativity and teamwork
• Lectures and demonstrationsIntroduction to steps and methods before practical implementation
• Weekly presence supervision and individual consultationEnables discussion after design steps and support for lab setup
• Practical assembly and testing of a lab prototypeApplication of the designed circuits and measurement methods on real hardware
