Objectives
After completing the module, students can:
- understand the steps and tools required to construct real electronic hardware to perform the specified tasks,
- understand the procedures for designing and implementing power converter systems,
- perform the project management tasks required to develop a power converter,
- evaluate the interactions between active, passive, and parasitic components in a power converter,
- construct and test a power converter system,
In addition, students will acquire practical lab skills such as measuring currents, voltages, and power with oscilloscopes and sensors, designing and winding magnetic components, soldering electrical components, systematic troubleshooting of hardware setups, and awareness of safety considerations whenever testing electrical equipment.

Description
This is a project-based course where the students will develop, build and test a power converter.
The main contents are:
1. Electrical and thermal design of a DC-DC converter.
2. Electrical design of an electromagnetic compatibility (EMC) filter.
3. Selection of power semiconductors and their gate drivers.
4. Calculation of power semiconductor losses and cooling requirements
5. Design of a high-frequency transformer.
6. Design of an inductor.
7. Selection of capacitors and EMC filter passive components.
8. Design of auxiliary circuits.
9. Design of a printed circuit board (PCB) for the implementation of the designed DC-DC converter.
10. Introduction to design review practices.
11. Construction of a laboratory prototype.
12. Testing of the prototype.
13. Analysis of the achieved results.
The course will be taught as follows:
The projects shall be done in teams of two or three students, who will receive a set of specifications and guidelines to perform their respective projects.
The tasks will be presented using slides and/or handouts. The students then execute the design tasks using their computers or hardware provided by the academic supervisors and CAD software available from TUM. Typical design tasks include the definition of power circuits, the choice of power components, the design of auxiliary circuits (gate drivers, current/voltage/temperature sensors), the design of magnetic components, the design of the cooling system, estimation of the lifetime of some components, the design of a printed circuit board (PCB), and the design of the mechanical assembly.
A feedback session will follow each design task, and a redesign can be done if necessary. The final construction of the power converter will require ordering electronic components and printed circuit boards. The realization and testing of the designs follow.
Support for students will be available during the weekly contact hours. The work results will be presented and discussed amongst all participants, allowing for experiences to be shared. Finally, a final report on the work carried out must be delivered.
