Subject fundamentals
After five decades of technology and applications, the field of 'Power Electronics' is to be integrated within the larger matter of 'Static Conversion', as requested by the newest targets of efficiency and compatibility in the growing-up renewable energy market. The matter is presented accordingly with, providing proper state-of-the-art knowledge while holding a deep reference to the fundamentals, for a good capacity of the future engineer to be autonomous in the continuing self-education requested by the continuous technological evolution, nowadays pushed by the renewed energy market.
Expected learning outcomes
Knowledge and understanding of commutating (non-linear electrical) circuits analysis.
Knowledge and application of comparative design analysis of power devices and conversion structures (semiconductors, reactive power devices, cost analysis for phase and hard switched power converters). Particularly on the calculation models of power loss terms and overall efficiency.
Knowledge of characteristic devices and transducers.
Knowledge and design application of control requirements and techniques, particularly the digital ones in Pulse-Width Modulated hard switched converters.
Prerequisites / Assumed knowledge
Basic and advanced electrotechnics, basic electronic components, fundamentals of dynamics and control of electrical systems, concepts of safety and electromagnetic compatibility.
Contents
1) Introduction.
2) Analysis and design of Basic functions, structures, semiconductor and reactive power devices.
3) Phase commutated converters
4) Hard-switched and multilevel converters.
5) Control properties and limits for PWM converters.
6) Voltage-supplied inverters and static converters.
Delivery modes
In addition to lectures, the course programme includes laboratory activities and computer simulations:
- Lab on power semiconductors and industrial power converters adopting Intelligent Power Modules.
- Experimental lab on hard-switched IGBT power circuits (H-Bridge).
- Design calculation and exercises (DC/DC power converters).
- P-Spice simulation of power converters.
- Closed-loop control simulation of power converters and PWM techniques.
For each lab students should freely associate in small working groups. One of them working on presentation and explanation of the lab, the other ones freely selecting and reporting on specific items well related to the lab. Written reports must point-out the contribution of each student within the working group.
