Prerequisites: In addition to basic knowledge of mathematics and physics, the course makes use of concepts in the fields of circuit theory (properties of electrical networks and fundamental theorems of network theory), electronics (electronic devices, operational amplifiers), and automation (feedback, stability, frequency response, Bode plots).
Target skills and knowledge: The main goal of this course is to make the students familiar with the analysis of switching converters, by providing them with the theoretical and practical tools necessary to design and realize high frequency conversion systems, with reference to dc-dc converters.
Examination methods: The final examination is divided into two parts:
1 - written test (Moodle quiz)
2 - oral test
The reports regarding the laboratory activity must be presented before the examination.
Assessment criteria: The evaluation criteria are based on the acquired ability in the analysis and design of switching electronic systems.
Course unit contents: - Introduction: description of the course content and organization. Example of power converter systems.
- Power devices: diodes, MOSFETS and IGBTs.
- Conduction and switching losses and thermal considerations.
- Review of converter modeling.
- Peak current mode control: modeling and design.
- Average current mode control.
- Isolated converter topologies: Forward, push-pull, half-bridge, full-bridge and flyback.
- Review of magnetic properties of material: inductors and transformers.
- analysis of high-frequency transformers: skin and proximity effects.
- Inductor and transformer design considerations.
- Input filter design.
- Snubber circuits.
- Layout considerations.
- description of MATLAB/Simulink and PLECS software and their use in the simulation of switching power supplies.

Laboratory activity

- Dynamic begavior of a Boost converter with peak current mode control.
- Losses analysis of a Boost converter.
- Measurements on a flyback converter.
- Measurements on a Forward converter with an active clamp.
Planned learning activities and teaching methods: The course is based partially on lectures with the use of a standard blackboard and slides, and partially on group activities on specific arguments.
A laboratory activity is included in which students have the possibility to test real dc/dc converter prototypes, comparing measurements with theoretical expectations and simulation results.
Additional notes about suggested reading: Didactic material will be made available in the course's web page (Moodle)
