Syllabus

Common characteristics of the Integrated Course unit

Prerequisites: For the successful achievement of the course objectives, basic knowledge of Electrotechnics (electrical circuits and magnetic components), Electronics (analog electronic circuits, operational amplifiers, semiconductor electronic components, digital circuits) and Automatic Control (dynamic analysis in time and frequency domain, feedback systems, stability analysis, synthesis of regulators) is required.
Target skills and knowledge: Provide the student with theoretical and practical knowledge in the field of power electronics. Provide knowledge concerning power semiconductor devices, high frequency magnetic devices, the main power electronic circuits and related control techniques. Develop the skills to analyze power electronics converters, to choose the main components and to estimate losses and efficiency. Develop the skills of regulating electronic power systems by means of analog and digital controllers. Develop the knowledge of designing analog electronics for the implementation of analog controllers and signal conditioning from sensors used in power electronics.
Develop the skills of simulating an electronic power circuit and making measurements on it.
Develop the skills in the adoption of power electronics in mechatronic applications and in renewable energy systems.
Examination methods: The verification of knowledge and skills takes place through an oral exam, which is carried out in two phases: the first phase corresponds to the first module and the second one to the second module. In each phase, there will be two questions: one related to the main topics of each module and the second one is related to the reports on the simulation and laboratory experiences carried out during the course and on the in-depth analysis of the delivered reports. The reports must be sent to the teacher within two days before the oral exam. With the individual relationships, the ability to display the analyzes carried out through a technical report is evaluated, in addition to verifying the rigorous methodological approach. The oral examination verifies the skills and abilities acquired in understanding the operation of the power electronics circuits, of the relative main components (power devices, magnetic elements, power converter circuits, analog electronics for signal conditioning and analog controller, etc.), the related control techniques and some main industrial applications. The overall grade will be given by the arithmetic average between the first and second phases of the oral, eventually rounded up.
Assessment criteria: The evaluation criteria used to evaluate the knowledge and skills acquired are:
- completeness of the theoretical knowledge acquired on the course topics;
- level of independent thinking acquired in the analysis of power electronics circuits
- demonstrated ability to apply theoretical knowledge for the development of dynamic models of converters and related control structures
- ability to understand power electronics circuits through simulation tools
- rigorous methodology on presenting the topics discusses during the oral examination

Specific characteristics of the Module

Course unit contents: 1. Introduction of power electronics circuit. Analysis of the specifications, design of the main components (switches, diodes, inductors, capacitors). Driver circuits.
2. Analysis of static and switching behavior of power devices (power MOSFET, PiN and Schottky diodes, BJT, IGBT, SCR). Design of high frequency magnetic components (inductance and transformers). Analysis of losses in electronic power circuits.
3. Analysis of DC-DC converters: Buck, Boost and Buck-Boost. Study of the CCM and DCM modes of operation. Calculation of losses in the converters and design of passive components (inductances and capacitances).
4. Study of isolated DC-DC converters: Forward, Push-Pull and Flyback.
5. Snubber circuits for the reduction of stresses in power devices during switching: turn-on, turn-off and overvoltage snubber.
Planned learning activities and teaching methods: - Lectures mainly on the blackboard also with the support of computer material (power point files prepared by the teacher or slides associated with the textbook)
- Exercises performed on the blackboard
- Video (about 12-14 min) performed by the teacher on exercises and simulation examples
- Exercises performed with numerical circuit simulations (LTSpice)
- Experimental laboratory exercises (in a teaching laboratory of the University)
Additional notes about suggested reading: Teaching material (additional textbooks, exercises, videos, component data sheets, simulation models, etc.) through the "moodle" platform (https://elearning.unipd.it/dtg/)
