Students can analyze cooling requirements and design the cooling system for a discrete power electronic system. They are able to design for manufacturing, explain the most important process steps in automated and manual PCB assembly processes and manage the electronic component supply chain for the Bill of Materials of their own design. Students can assemble PCBs and test a power electronic circuit in the lab. They are familiar with modern prototyping techniques and are able to build and test the systems they have designed in the first part of the course. This includes the development of a suitable test strategy according to the requirements and specifications of the given power electronic system and handling of state-ofthe-art laboratory equipment. Thus, students are ultimately able to analyze and test a power electronic converter, identify the different components on the PCB and point out design weaknesses and possible improvements for thermal and EMI performance by PCB design.

ILV "Power Electronic Concepts & Circuits"

• Implementation of a converter
The layouts designed by the students in DPES1 and the Bill of materials will be
analyzed; chosen components will be ordered; the circuits will be built by
manual assembly and a reflow process will be applied.
• Test of a converter system
The system built will be tested according to verification plans developed by the
students and a technical report will be created documenting the results and
interpretation.
• EMC & noise, parasitic impedances & effects
Analysis of EMC effects in power electronics designs, coupling effects, PCB
Layout analysis for EMC.
• Thermal modelling, passive & active cooling
Passive and active cooling concepts; thermal models and electro thermal
coupling effects; implementation of cooling for student converter designs.
