Syllabus
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: Knowledge and skills to be acquired:

- knowledge of main DC-DC converter topologies, isolated and non-isolated;
- working principles of main power electronic devices
- knowledge of DC models for the steady-state analysis of power converters (voltage conversion ratio, device voltage and current stress, etc.);
- knowledge of linear equivalent models for the transient analysis of DC-DC converters;
- knowledge of multi-loop control approaches based on an inner current loop;

- ability to design both power stage and control part of a generic DC-DC converter;
- skills in using simulation tools (MatLab/Simulink, PLECS, SPICE) for the design verification;
- ability in the critical evaluation of experimental measurements on DC-DC converter prototypes, with reference to the theoretical analysis and simulations.
Examination methods: The final examination is divided into two parts:
1 - written test (Moodle quiz) based on simple exercises on analysis and design of DC-DC converters;
2 - oral test.
The reports regarding the laboratory activity must be presented before the examination.
Assessment criteria: The used assessment criteria are:
1. knowledge of main DC-DC converter topologies;
2. knowledge of analysis techniques of DC-DC converters;
3. knowledge of DC and AC modeling techniques
4. ability to apply the acquired analysis techniques to novel conversion topologies;
5. ability to apply design techniques seen during the course;
6. ability to evaluate experimental measurements, with reference to the theoretical analysis and simulations;
6. skills in the use of simulation tools.
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:
- 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.
Quizzes on Moodle will be activated to help students in the self-evaluation process.
Additional notes about suggested reading: Didactic material will be made available in the course's web page (Moodle). It includes:
- slides used during the course;
- exercises with solutions;
- quizzes on Moodle for self-evaluation.
