POWER ELECTRONICS

Second cycle degree in ELECTRONIC ENGINEERING

Campus: PADOVA

Language: English

Teaching period: Second Semester

Lecturer: LUCA CORRADINI

Number of ECTS credits allocated: 9


Syllabus
Prerequisites: Besides fundamental concepts of mathematics and physics for electrical engineering, the course draws on basic notions of circuit theory, electronics, and continuous-time and discrete-time signals and systems.
To better tackle the topic of digital control of power converters, basic concepts of digital signal processing are also useful. These more specific notions will nonetheless be briefly covered during the course.
Examination methods: Written exam performed at the computer, followed by an oral examination.
Part of the final score is determined by laboratory assignment reports turned in by the students.
Course unit contents: - Introduction to power electronics;
- dc-dc Buck, Boost and Buck-Boost converters; steady-state analysis in continuous and discontinuous conduction modes;
- analog control of switched-mode power converters; averaged and small-signal modeling; standard PI and PID compensator design;
- digital control in power electronics: overview and main control platforms; discrete-time modeling techniques; standard digital PI and PID compensator design;
- high-quality power factor correction (PFC) rectifiers: main topologies, control techniques and dynamical models;
- single-phase inverters: topologies and modulation techniques;
- three-phase inverters: square wave, PWM and space vector modulations;
- laboratory activity: hands-on experiences on a dc-dc converter; controller design and experimental verification;
- use of MATLAB/Simulink/PLECS for system-level simulation and design of converters.
