Teaser/short description: Semiconductor power switches are the main component of modern Power Electronics circuits. This course presents the main power switch types used in traction applications, starting from giving a design perspective and ending giving technological insights. The course develops on three days. The first one is mainly devoted to the semiconductor part, the second one on the packaging part, both days looking both at design and technology. The third day is mainly groupwork where participants will design an application-specific automotive module.
Description:
Day 1
Lecture 1: 08.30-12.00 (F. Iannuzzo, 3h)
• MOSFET, Diodes, and IGBTs.
• Power electronic devices switching theory
• Emerging (wide bandgap) technologies.
• Power loss calculation.
Lecture 2: 13.00-14.30 (F. Iannuzzo, 1h 30’)
• Condition monitoring
• Life prediction.
Lecture 3: 14:50-16:30 (E. Hoene, 1h 40’)
• Introduction and motivation for WBG electronics
Day 2
Lecture 4: 08.30-12.00 (E. Hoene, 3 h)
• Introduction on packaging techniques for modern semiconductor power switches.
• Challenges in terms of power density, stray inductance/resistance and reliability.
• Modern interconnection solutions: copper bond wires, low-profile packaging, bondless packaging, etc.
• Group work, part 1: 13.00-16.30
Day 3
Group work, part 2: 08.30-12.00
Final lecture: 13.00-16.30 (F. Iannuzzo, 1 h; E. Hoene, 2 h)
- Project presentations by groups, Collective project verification and discussion.
Prerequisites: basic knowledge of circuit theory
Form of evaluation: the participants will be grouped and asked to work in team on a real design. Groups will compare and deeply discuss the achievements and the design choices in the final 1-day lecture. Attendees are asked specific questions about the developed design to be answered individually.
