Prerequisites: The course makes use of some basic concepts and results of circuit theory and signal analysis, in particular the harmonic spectrum of stationary waveforms and dynamic analysis of linear systems by Laplace transforms. Technologies and operating properties of semiconductor components are also referred to, as well as basic concepts of automatic control.
Target skills and knowledge: The course discusses the basic configurations of electronic power supplies, both AC and DC, and provides the fundamental competences needed to approach the analysis and design of switching converters, with- or without insulation, for a wide range of power levels and application domains.
The properties and application characteristics of the main power electronic devices are also analyzed, together with their driving circuits and operational limits (electrical, thermal, electromagnetic), with the aim to offer the student an overview of the practical application problems of power electronic components and systems.
The operational characteristics of dc/dc converters, both open-loop and closed-loop, are experimentally verified by a set of laboratory tests made on ad-hoc circuit boards.
Examination methods: Written examination: preliminary design of a dc/dc converter; laboratory test report,
Oral examination: discussion on the course matter.
Laboratory examination: setup and test of an experimental converter circuit.
Assessment criteria: The evaluation of the student preparation will be based on the discussion of the theoretical operation of power converters and their design criteria, and on laboratory measurements on converter prototypes.
Course unit contents: In the beginning, the course gives an overview of the many fields of application of switching power supplies, and their requirements in terms of electrical performances, efficiency, reliability, and environmental compatibility.
Follows a description of the most popular power electronic devices (diodes, Power Mosfets, IGBTs), with their functional characteristics, limits and application domains.
The main non-insulated dc/dc converter topologies (buck, boost, buck-boost) are then presented, their performances in the continuous and discontinuous operation mode are considered, the main control techniques based on voltage and current feedback are analyzed, and design criteria are discussed as well.
After an introduction of the high-frequency transformers structure and operation, the main insulated dc/dc converter topologies are then presented (forward, dual-forward, push-pull, flyback), their properties analyzed, and design criteria discussed.
The next subject relates to single-phase inverters (half-bridge and full-bridge), their operation and control methods.
Finally, after an analysis of the International standards limiting the harmonic injection in the public electric grid, the main topologies of power factor correctors (boost- and flyback-PFC) are presented.
Planned learning activities and teaching methods: Classes:
1.Introduction to the course
2.Power electronic devices (generalities about power devices: SOA, snubber, thermal aspects; diodes; power Mosfets; IGBTs; IGCTs)
3.Basic topologies of non-insulated dc/dc converters (introduction to dc/dc converters; buck converter in continuous conduction mode, CCM, and discontinuous conduction mode, DCM; boost converter; buck-boost converter;
4.Insulated dc/dc converter topologies (high-frequency transformers; forward converter; dual-forward converter; push-pull converter; flyback converter)
5.Bidirectional dc/dc converters
6.Control of dc/dc converters (pulse width modulation, PWM; feedforward voltage control; feedback voltage control; feedback voltage control with current limit; average current control; peak current control)
7.Ac/dc converters (diode rectifiers with capacitive filters; harmonic standards and passive filtering; power factor correctors, PFC; boost PFC; flyback PFC
8.Dc/ac converters (single-phase voltage-fed inverters; half-bridge inverters; full-bridge inverters; PWM control of inverter output voltage)

Exercises: preliminary design of various types of converters

Laboratory: experimantal verification of the operating characteristics of a buck converter (open-loop stationary and dynamic analysis; closed-loop voltage control and current control)
