Examination board not defined

Prerequisites: In addition to a basic knowledge of mathematics and physics, the course makes use of concepts developed in the courses of Circuit Theory (properties of electrical networks and fundamental theorems of network theory), Electronics (electronic devices, operational amplifiers), and Signals & Systems (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 pratical 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
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: - General concepts on Power Electronics
- static and dynamic characterization of electronic devices employed as switches: diodes, MOSFET, IGBT;
- basic dc-dc converter topologies: steady-state analysis (Continuous Conduction Mode - CCM and Discontinuous Conduction Mode - DCM);
- isolated converters: forward (reset R-C-D, active clamp and auxiliary winding), push-pull, half-bridge, full-bridge, flyback;
- average models in CCM and DCM and their linearization around a given operating point;
- direct duty-cycle control: design of PI and PID controllers
- double loop current controls: peak current mode, average current mode;
- analysis of high-frequency transformers: skin and proximity effects, approximated derivation of the low-frequency transformer leakage inductance, Dowell curves and high-frequency winding losses;
- snubber for switch overvoltage limitation at turn off (clamping circuits);
- input filters: design criteria;
- laboratory activity: static and dynamic measurements of a boost dc-dc converter;
- description of MATLAB/Simulink and PLECS software and their use in the simulation of switching power supplies.
Planned learning activities and teaching methods: The course is based essentially on lectures with the use of a standard blackboard and slides for specific arguments.
A laboratory activity is included in which students have the possibility to test a real dc/dc converter and to design a controller.
Additional notes about suggested reading: Didactic material will be made available in the course's web page (Moodle)
